Offset shackles

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 .

Believe whatever you like, but there’s only a 1/2” of space between the front hangers and the frame rail. Unless you put the whole inside wall of the hanger inside the frame rail, it’s not a 3/4” offset.

The MP hangers require dimpling or cutting a hole in the rail to clear the nut welded on the hanger for the spring eye bolt, but it still doesn’t get you to 3/4” in the front. I used those hangers on my Duster, if you hold them up against the doctordiff hangers the offset is identical and it’s a 1/2”.
