Hey hemipowered2, I saw this posted in reference to your situation. This is someone else's suggestion as to the problem. I'm just posting it in the hope that it may help you out.

on 68-70 bbodys there are differances between dodges and plymouths
when you change out the frame rails they are the same.

what is not the same is the mounting points of the rear springs
when you change that part you need to know which one you are using..

the rear springs are the exact same on both ply and dodge
what is different between dodge and ply
is this and i will use ebarf to show you...

thats 2 different parts....one for dodge and one for plymouth
obviously when he changed the rails he changed his mounting position
he just needs to use the right parts that will fit so
it will go back together correctly
