Stock rear leafs with Hotchkis front coils?

I had the same issue on my older 71 Camaro, SFC would hit/drag.

I corrected this on my ‘72, just used a mild piece of 2x3 .125 wall and grafted them in and followed the natural rear upward angle of the sub frame, all tucked above rocker pinch and you grab all of the cross rail and floor area and finished it in the torque boxes all from the inside.

Not noticeable from looking underneath, and with the carpet and floor mats, don’t notice on the interior. Big help in torsional to boot.

 

I cut out almost 3” off the hooker super comps to get them tucked up, lots of work, but no dragging.

 

Please me more where to get these adjustable shackles.... sometimes I like the "rake" look other times I like the " low end" look.

 

PTFB's shackles have two sets of holes to raise the rear and/or add anti squat (alters the instant center)

 

yeah I get about a 1/2" of height tunability out of those.

I also got some rubber material from McMaster Carr and essentially made custom spring padd... doing so allows me to tailor another 3/8 to 1/2 of height up or down by making either the top or bottom pad thinner or thicker. though if I make the top pad thinner I have to thicken the bottom pad by the same amount to keep the overall stack up thickness the same and vise versa.

this plus the adjustable shackles allowed me to bandaid the sagging springs temporarily until I install my 1LEs. actually have been running like that for a few months now without any adverse effects.
