Here is a solution that would allow for the stock bell to be used (post #36):

I have a part number for a shifter that I thought would work with a TR6060, but I don't know now. There should be one though.

Don't forget about the output flange adapter and custom driveshaft as there isn't a slip yoke on the TR6060.

Also, there is no speedometer output so you will need to come up with a secondary means for showing a road speed.
