So I'm putting a few miles on my reassembled stroked '66 with a newer T5 and I'm noticing that the shifter rocks side-to-side under hard acceleration particularly in second gear. Not particularly confidence-inspiring as I'm flying down the road. The transmission mounts seem intact. The motor mounts seem ok too, but is there a better way to inspect or measure them? My only other speculation is that the pinion angle might have been disturbed with the recent reassembly of the car. Anyone had a side-to-side rocking in the shifter, and if so, what was it? Thanks!
