my road runner leafspring still won't hook up. i bought all after market parts, and im 1/2 inch from hooking up. do i redrill the holes in the hangers to fit the springs. or keep paying for someone to stare at it for anouther 10 hrs???

How about a break down of the parts you bought. If you have super stock springs and are trying to use O.E.M hangers this may very well be your problem.

im using a set of springs from spings and things they are the hemi ones.. not the super stocks. the hangers are a stock replacement.

Where exactly does it not fit? The rear of the spring or the front of the spring? I'm not sure what you're talking about.
The rear suspension should have enough play to move the springs side to side to get everything hooked up? 1/2 inch isn't that far??

If everything came from them I would contact them about it first. Never used anything from them myself.

its the front to the back. it won;'t hook into the shackel mount its too far forward. i need to know if removing the tube and moving it forward by 1/2 inch is the right thing to do.....

i think you need to put rear end housing and springs together then mount the front of the spring to front spring hanger location,then take a jack and jack up the assembly by the center of housing and this should relax the spring to get that extra 1/2" you need, i've had to do this on a couple of sets of superstock springs to get them to hook up. hope this helps

the junk man is right!!!

It's way easier to get the old flat springs out than to get the new arched ones in. I've had to put the front bolt in, push the rear shackle as far forward as you can, and put a floor jack under the spring to flatten it a bit. Make sure you don't lift the car off its jack stands.

Maybe you can back the nuts off the front spring hangers until they are flush with the ends of the studs, then pry the hangers rearward to hook up the rear shackels, then tighten the front spring hanger studs back up?

you may have dodge springs. they are longer than plymouth.

i took the same springs and put them on a 1970 rr that had never had the rails changed in. and they went right in. thats why im lost when i go to install them in my car. the rear cross member seems to be dead i just don't understand why i cant reach the shackle holes with out moving the holes forward. the springs seem to be short. but if they went right into anouther 1970 rr id say somethings wrong with my frame rails or my shackle mounts. the do sell ones for a station wagon i heard were different. im sure i have the right ones here.

Do you have your old springs laying around anywhere to compare them to? You might want to measure along the arc of the spring and see if what you received is indeed too short. When I bought replacement springs from ESPO they went right in.

were the rails replaced along with the rear crossmember?

It sounds like the springs must be incorrect. I cannot imagine moving the hole in the frame for the rear shackle to bolt up! That would just be jury-rigging it to fit instead of solving the problem. Once installed, the hole in the spring leaf for the rear shackle should actually be a little past the center of the hole for the shackle in the frame. The rear shackle angle from the frame to the spring has to be angled back like in the attached photo so that the shackle can rotate forward on takeoff for the springs to work properly. If you bolt up your front hangers and jack the rear up, the rear shackles should fit relatively easily. If your shackle is laying all the way back and still is missing the hole by a 1/2", you have a problem with the length of the springs or the frame. Even if it bolted up, if the rear spring eye is in front of the mounting hole in the frame, the spring will be bouncing up into the frame when you go over bumps...I would start off with some measurements from the rear hole in the frame to the front spring hanger mounting flange and post the measurement here and someone will verify it for you. I will bet the springs are just not the right ones.

Were the rear frame rails on the car replaced? And if they were did you replace them with stock plymouth frame rails? I believe (am sure) there is a difference between dodge and plymouth frame rails as far as rear spring mounting locations. The front hanger is also different but that would move your spring location back, not forward if you were using front hangers from a dodge. So I wouldn't think that was the problem. But if you replaced the rear frame rails this may be something for you to look at. Just my Scott

the frame rails were replaced with a 49in set and a new cross member was installed the distance between the 2 are correct. we used a jig off a 70 rr.

What were the new rails out of?
Just throwing around ideas here but maybe the rear shackle tube is in different locations for different B Bodys???

i bought them from auto body sp. they are direct replacements. all the parts came from them except the leaf springs there from spings-n-things.
