Scuncio Chevelle ex-L78

[Too Many Projects]

When loosening the control arm bolts, are you doing all 8, or only 4 ? Also, can you turn the bolts to know they aren't seized in the bushing sleeve ?

Yes, I loosened all 8 control arm bolts (uppers are a pain) - but I didn't really feel as it was necessary, as it hasn't been that long since i rebuilt the rear suspension and everything was tightened then at ride height.
But with loosening the bolts and bouncing the rear of the car up and down - the 1' lowering springs didn't lower my car over 3/8 inch. Could that be because the springs in my car - that I got from a friend of mine - really are stock 1970 Chevelle SS springs with 170,000 miles on them, and they have sagged some? But if that is the case, why is my car still to high in the rear?
Oh well, 2' lowering springs are on the way - so we'll see.

So I got the 2" lowering springs and installed them - they worked great - car now sits level (as measured from the top of the rocker panel to the level garage floor).
Test drive showed no signs of wheel-hop. Of course this was not on a prepared racing surface where I will get better traction - so we'll see. But I do hope the wheel-hop is gone.
ALSO: since the car sits different now - the leak at the pinion seal runs down the bottom of the rear end housing, it's not dripping off the dust shield on the pinion yoke. As soon as my mechanic gets to me, I think he is going to re-do the pinion seal and put extra sealant around the outside of the seal. I certainly hope that will fix it this time.

please show us how it sits with 2" lowering springs and what brand and PN on springs

Sure Zman1969. The springs are BMR SP015R. There is also a revision code letter at the end of the part number on the spring (it doesn't show up when ordering) - I don't remember right off the top of my head what it was on my springs.
