Not entirely so , I had to dimple the frame and eggshape the holes in my car to get the front ones in (w/ a hammer(> almost 3/4" .
I bought them off a member on here , that said they wouldn`t work on his car. I got no idea who made them tho . I have 295 65 15 drag radials on a 68 barracuda fast back using them with the standard tricks.
I bougth a complete reworked dana 60 w/ a Detroit locker in it, set up 1" narrower than stock, w/ disc brakes. Couldn`t pass up the deal back then. The builder welded the spring pads in exactly 3/4" narrower than a stock A body, it dropped right in using no prying or pushing the springs and is centered perfectly.
Stil lneed bigger tires tho---
Wish I could post pics on here but some reason I can`t .
