Which ones go on which car?? Originals only please, as I've heard the reproductions are mixed up. How many coils does each spring have? Tav

The factory kept replacing the hoods under warrantee because they bowed in the middle. Finally the factory came up with the fix. Take the hinges off and use a prop rod. I did that to mine and it flattened right back out to match the fenders. My hood hinges for my AAR have 33 coils.

Part # A0112B I painted them to match the car, but because of hood warpage issues, they are rarely ON the car. Mostly they just lay around here on a shelf. These reproduction AAR springs measure 36 coils long, 1 3/8 outside diameter, and 6 3/4 length not including hooks. That's remarkably similar to original T/A hood springs. I started to look into this once before when I first bought these springs, but I've lost my notes from back then. From what I could tell, it looked like the repro spring manufacturer had mixed up the T/A vs. the AAR and was selling them to various distributers mislabeled. Now I'm working on a T/A, and am considering ordering a set of repro T/A springs just to see what I get. Will someone with original AAR springs please take outside diameter and length without hooks measurements and post them here so that we can compare. Thanks Tav

I have a set of NOS TA hood springs, purchased from Chrysler in the 70's, no dealer sticker but I know who bought them. They measure 6 1/2" long, 36 coils, 1 5/16 OD, the spring thickness is .180 . The spring thickness is more on the TA springs I have, not sure if the over the counter springs were the same as the production line springs, they are gold cad plated. The hooks are also different between the two springs! These springs are unique to just the AAR and the TA.

I've checked the spring thickness of my reproduction AAR springs, and it's .19 (thats with paint). Again, it more closely resembles an original TA spring. Anyone know who makes the reproduction springs? I had that info before, but like I said, I've lost my notes from back then. I'm going to look into this further. I'll post updates here. Tav

What would be the result of putting the springs on the wrong car? When I ran my reproduction springs (resembling T/A springs) on my AAR, I didn't notice any adverse effects other than hood warpage. I suppose the warpage would be more severe since these springs are for a heavier hood. Would using AAR springs on a T/A hood then result in less warpage? It would still warp right? Tav

Still, the spring they sent me is like a TA spring, not an AAR spring. I'm going to be calling them about this and see if I can get it all sorted out. They've been misleading their customers for at least six years with this mix up, and it needs to be fixed. Tav

cataclysm80 OP master C Joined: Oct 2006 Posts: 4,165 Florida	Yes, My repro AAR hood had repro TA springs on it for about a year and it got pretty warped. (that's when I found out about having the wrong springs) Took em off and been using a prop rod ever since. Hood flattened out over the coarse of a month or so. Heat helps it flatten out, if your in a hurry you could park it in the sun. I've also heard of a guy putting sand bags on the hood cause the weight helps too, but it's not neccesary if your patient. Another note: if you don't like the prop rod look you can bend a solid bar to replace the spring. Just make it so it hooks around the same spots the spring would and make it the proper length to hold the hood in the open position. Should only need it on one side. Just open the hood and install the bar, same procedure as a prop rod, but it doesn't take up as much space in the back seat. You can even paint it to match your car, and few people will ever notice the springs aren't there. It's not up in your way like a prop rod. JUST ONE REALLY IMPORTANT THING! DON'T FORGET IT'S THERE AND TRY TO CLOSE THE HOOD! (Crack!! ) Tav

If so, major screw up and all your perseverance has paid off & in a big way 'cause there's gotta be alot of owners that read this and can now have all they need - all provided here & by you & the other great members - to measure the part and visually examine its the correct piece or provide exact measurements & coil count to their supplier before its sent. Great detective work & your a great asset here & for alot of reasons.

One is 23 coils, used on 70 cuda/barracuda only. The other one is 18 coils, (wound from a thicker wire) used on 70 challengers, and all 71-74 E-bodies. This applies to all steel hoods (flat/rally/shaker). Perhaps we've counted our coils differently, It can be tricky deciding if you should count the first and last ones with the hooks on them.

What it does is exactly like the above post says, it puts stress/ pressure on the front ( leading edge ) of the hinge when it is closed. That stress then weakens the fiberglass which thus causes the WARPAGE. If you show your car then I would open the hood and then install the springs, then take them back off before closing the hood. But myself I would use 2 prop rods at the front. Kev

I say while it's on the car because I don't think you would be able to open the hood hinge in your bare hands while it was off the car. You could also mount it in a vice. The point being.....how much pressure? Quite a bit. Better yet...remove the sping from the hood hinge and try to stretch the spring. Frank

Once the hood is open there is NO PRESSURE exerted on the hood. Thats why the hoods warp, from the pressure of the spring pushing up on the hood while it's CLOSED. Frank

You have to understand that the hood is a "certain " length. now you have to relize where the pivot point of the hinges are. So based on that distance from the hinge to the front of the hood is weight and leverage. So based apond that , length weight and distance to the hinge pivot is the reason why you DO GET THE WARPAGE ! from the force of the spring trying to raise the hood, but it can't because the hood pins are holding it down. Thats why I say leave the stupid springs off! Kev

I quess I didn't write it like I was trying to say it, so you would understand what I meant. No the hood DOES NOT FLY OPEN ! But yes when the hood is CLOSED those springs are applying upward (constant) pressure on the hood between the hinge and where it is held down at the pins. Ok you guys do what YOU want concerning the use of those springs on your cars , but aleast you know what MY opinion is of them. The hood on my T/A was screwed up because of those springs back in 1972 and to this day is still messed up ! Good Luck To All! Kev

As far as I know, I wasn't able to get the manufacturer to change the labeling, so they're still mislabeled. Tav

I just purchased a set of Year One AAR springs and after rereading this thread, I think I may just return them and make a steel bar to hold the hinge open as described. And return the overpriced springs, as I know they were half that not long ago. Thanks AAR cuda 71 rag challenger

I think these repro springs used to cost between $50 and $60. Has the price gone up? Does Year One still have the MOPARTS15 discount going on? Tav

I saw a few places outside of Moparts where people were still having trouble figuring out what hood springs to use on the Mopar Trans Am cars. I looked at Year One again, and they STILL have their springs mislabeled. That's at least 15 years of misleading people. Vans Auto seems to have their springs labeled correctly, which is nice. Finally a little progress. Hopefully other places will start labeling their parts correctly in the future. This picture should make it easier for everyone to know which spring is for which car. Tav

The T/A hood has a big scoop and also goes all the way to the front of the car, so the T/A hood is heavier than the AAR hood.

A 4 barrel AAR hood assembly? Is that from one of the factory sponsored race cars? That sounds like an interesting story.

I went to Van's website, it shows one, but no description. His ebay store doesn't list one, it does list a AAR one. I messaged him, hadn't heard back yet. Also, the spring I have definitely isn't an AAR spring, not sure what I have, but for sure it is either too long or not enough tension. Not worried about hood bowing. update: just heard from Van's, he doesn't have any T/A springs....... Last edited by varunner; 06/16/20 09:30 AM.

Hoover auto parts has them, but they have the usual mix-up between T/A and AAR. With shipping, they're approx. $150. Myself, I'm holding off on paying that.

Look at your hinges, they have pre-drilled holes in them. Take a round stock think 5/16" bend 2 90's in them. Put these in the holes, will have to measure to get an exact length. But it's much safer & looks better than a "broom handle." Sorry wished I had pictures to show exactly what I mean, but our TA is gone. But a great fix to a simple issue. Thanks, Ken
