Did one of these years ago but cannot for the life of me remember exactly what I did. I know I can press out the receiver for the crossover shaft from the gear change quadrant and press in an earlier right shifter shaft from an earlier 650/750. I think I either had a bushing made to receive the earlier and smaller diameter of the inside of the shaft or used one from an earlier inner tranny cover. I am sure I am missing something. The end result will be putting a 1976 750 Bonneville motor into a 1967 frame. If anyone can help jar this old brain it would be very much appreciated
put a plug (i used a freeze plug) in the hole on the primary side where the shift lever came through the inside of the main casting. Otherwise engine vents back into gearbox. Been there, done that. I kept the original 750 inner cover and used an earlier outer if I remember. Make sure you swap the pawl assembly.
Yes, gear change quadrant and cam plate operating quadrant. I did this back in '94 or so but on second thought I I did use the T140 inner cover and only used the earlier outer cover to make the swap. Holes were plugged internally.

Still need to change the gearshift quadrant ( pressing out the crossover shift shaft) as well as change the operating quadrant right?
