All of the above and don't forget fat bars require good shocks. Don't skimp there. I run MP 1.12" with RCD Bilsteins on my E-body Barracuda. Leaves are old MP XHD's with the extra RH leaf, 80's vintage made in USA examples. I also have SFC's and torque boxes. Small block/Auto.

A similar formula and some offset UCA bushings, and you'll be impressed, especially with your long wheelbase. I also added shims to the P/S pressure valve to reduce the assist pressure. Didn't do much for the road feel, but did increase the effort, and it feels more precise to me, which adds to my confidence.

Mopar Mitch has posted his $0.02 on the Tbar subject in the forum quite a few times. I followed his guidance and found I agree. Worth a search
