Well, sorta. We’ve mocked up a stripped TH200 with a bare block and a D&D spacer, modified the orig crossmember mt a little/flipped the side brkts over/elongated the frame holes/ and moved it up one hole in the frame-I guess to the manual trans bolt holes, bolted it up with mtr mounts, pushed out the tunnel a little with porta-power/heat/hammer to get about 1/2″+ clearance min at all locations-can get more if needed, used a short gm mount and I think we have a good angle to the center support. Haven’t sourced a th200 detent or set up the linkage. Want to use orig shifter and should be able to, and will need to shorten the driveline to the center support. Rather than lighten the roto flywheel I am using the flexplate from 63cutlass above.
