Hey guys, just got an 8.25 rear for pretty cheap (~$80) from an off-roading buddy of mine; came out of a Jeep Cherokee XJ. Pretty sure it was working fine when pulled, he just wanted something bigger for wheeling. Also it has 3.55 gears in it which would be great for my '70 Duster street machine or basically anything with Overdrive but I want 3.07s for my 5th Avenue to keep it a nice highway cruiser. So my main question is, aside from having the Jeep-style shock mounts cut off and the spring perches flipped what needs to be done regarding the Iso-Clamp setup? Do I need to keep them unless I swap the leaf springs as well? I'm trying to keep it as low-budget as possible and while it would be nice to have new rear springs (mine are too soft and of course sag a bit) I don't exactly need them. I've heard there are poly inserts to replace the rubber pads in the Iso-clamps, I think it would be easiest to go with those and maybe swap out the leaves under the main one kind of like a bastard-pack setup just to stiffen it a bit? What do you guys think?
