Is there much difference between the Hurst Powertrain & the SST shifters for Tremec swaps into '71-'72 B bodies?
I'm mostly concerned about driveshaft yoke clearance.
I would tend to think not, as the Hurst TKO shifter/transmission designs are basically copies of the early Keisler designs, and SST has continued with the same basic Keisler design, but if I was looking for an upgraded shift tower, SST would have the later (3rd gen) designs with internal upgrades which help eliminate the "buzzsaw" effect at certain RPM ranges, as well as better detente of the shift gates, as well as better shifting effort overall
