Hello all- I am new to the group, and just like all of you, I love my cat. I have a question, but first let me give you a little background to what led up to the problem. I have a '67 standard that I am about 80% done with the ground-up restoration. I am going the restomod approach, with a high revving small block 4-speed, and 4:11s out back. I had the leaf springs off the car for about a year and a half, and never took the packs apart. When I reinstalled them in my car, I eliminated the rubber sandwich mount, and used stang shock plates instead. I replaced the shackles with stock style aftermarkets. Heres the problem: My car sits very high in the rear, as if the springs re-arched themselves while they were off the car. I had to load up the trunk with about 15 8" concrete blocks to get it to squat down enough to bolt up the kyb shocks! When looking uder the car, the shackels point straight up and down perpendicular to the floor, instead of towards the rear. The engine and trans is in the car, but no doors, decklid, interior, or rear bumper. I weigh 230lbs, and if I stand in the trunk, it only squats down a little bit. The rear suspension is very stiff. I can't believe that adding the interior and sheetmetal that I mentioned will make that much of a difference. Heres the kicker- before I tore it all down, the rear end actually sat a little lower that the front, and had air shocks to level everything out, and give it a slight rake. Has anybody else experienced this? Whats going on here? Sorry this is so long, but I wanted to be very specific. Thanks to all.
