I just put a Moser 12-bolt on my 96 Z28 and the swaybar is touching the bottom of the 12-bolt pumpkin.
Do I need to add washers to the U-joint that ties the swaybars bushing in place?

I know this is obvious, but is the weight on the wheels?

 

I have the car suspended on a lift. The wheels are not touching anything. I will see how it sits on the ground. There's just barely some clearance between the swaybar and the bottom of the pumpkin. I may be fine, once it sits on the floor. we'll see.

 

I hade the same problem with a strange 12.
my sway bar was hitting the diff cover on the bottom of it.
I simply ground down the diff cover a bit and everything clears nicely now.

Good luck Mike
