FWIW, the 4" upper "ear" was because the CR factory shock was not a stock MII, but a Monroe for a '70 full size GM. The Carerras, a little stiff at first, have been working fine.

Purchased lower control arms, and Carerra coil over kits from RCC in Ft. Worth, TX. RCC was very familiar with CR front suspension, and the shocks came with upper shock extensions to fit CR ears.

The single largest improvement that made friends with my alignment shop was Tom Beroths upper control arm bracket. Alignment could be set with shims, GM style, and stayed put afterwards.

Some improvements at the frame level that you might want to think about Don, would be to incorporate these brackets or mounting points for pper control arms onto the frame, and mounting points for strutless lower control arms.
