Usually if you can move the rear edge of the hood up & down when it's closed, it's worn teeth. The slop allows the hinge arms to move enough to cause the back edge to walk up. Worn pins will contribute as well, but if the pins are significantly worn, the teeth are usually trashed even worse.
It's also worth mentioning... I have people ask all the time, "How badly worn were my hinges?". Every set I've had apart, including clean, seemingly "good" hinges, had excessive clearance in the teeth.
The manufacturer of these hinges stamped the teeth, so they weren't a very precise fit from day one.
I weld them up & grind/sand them for a precise mesh.

Top one should do the trick:
20 turns 2.125 OD, .264 wire dia.
Lower:
19 turns- 2.095 OD, .242 wire dia.

Is the top spring the right one for the RT/ Ralley (Bulge) Hood?
Thank you!

70-74 Cuda w/o shaker= 3586088 (lighter than the longer hooded Challenger)
70-74 Cuda w/shaker= 3586092 (also used on Challenger with or w/o shaker.)
Turnaround is typically a couple days on rebuilding.

I'm not 100% sure... I haven't researched the late B-bodies that close yet. The pic is the two I've seen used on them most often.
The parts book shows the same number as used on the Challenger hood, however, I'm not sure that's what happened in production, as I've seen the heavier spring a number of times.

Thank for the info rick. So is it possible I have a spring problem ? Or do you think my hinges are wore out, As my hood stays up with no problem.
thank you for your help.

The 70-71 parts book is a bit confusing on the subject, but it does try to imply that springs are different from fresh air hood cars. The book doesn't even differentiate between the springs of 70 or 71 B-bodies and those hood hinge assemblies are entirely different. I noticed in the past some different 1970 hood springs and assumed that it had to do with which assm. plant the car was built at. Here's a pic and specs of what I had laying around.
Top spring: 21 coil, 1.81 dia, .215 coil 70 Sat. Lynch Rd built
Mid spring: 25 coil, 1.72 dia, .215 coil 70 GTX Air Grab St.L built
btm spring: 24 coil, 1.83 dia, .250 coil 69 Super Bee?
*notice how some of the coil ends end 180 degrees different than others

Yes, Dirk... the 70-71 parts book is confusing!! I'm compiling the various dimensions to see if I can make some sense of it all... might not be possible..  Thanks for those... Rick

Sounds like your hinges need some love...

Here is some E body Steel Hood spring info from one of my old threads...

I guess while I'm on the topic of springs, I'll post the data for steel hood springs also.
'Cuda sport hood: 24 coils, .215 spring thickness (with paint), 1 3/4 outside diameter, 5 1/8 long (without hooks)
70 Challenger flat hood: 22 coils, .240 spring thickness (with paint), 1 15/16 outside diameter, 5 1/4 long (without hooks)
Tav
Found this in another thread and thought I'd post it here also since it's relevant.

Actually for the steel hoods, there are two kinds of springs, I researched this in the 70-71 factory parts book, and confirmed it on cars I owned/parted. 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. Anyway, I thought I'd let everyone know this this needs looked into just a little more, and maybe a picture posted here showing a comparison.

It came from this thread about AAR & TA springs https://board.moparts.org/ubbthreads/show...part=1&vc=1
Hope that helps, I'd like to make some sense of this myself!
