Appreciate the input so far.
Are the spherical bearings that Global West uses the same or similar as the "Roto Joint" that UMI uses? Just wondering if it's a brand name thing.
After doing some homework, I've been leaning towards what Jason recommended above. Either the Global West or UMI with the spherical joints on the frame side and poly or Del-a-Lum on the diff side. I believe the diff housing comes with rubber bushings already installed.
Since the 12 bolt is a direct replacement, I don't see the need to spend the extra $ on adjustable uppers since the pinion angle should be good. I also prefer boxed control arms to tubular purely for appearance, so I'm leaning towards UMI pieces.
I have a sway bar from a '70 GTO in the rear I'm going to retain along with the Bilstein shocks.
Lowers: UMI 4041
