This page is to detail the 6 speed conversion process.  I purchased a kit online but it was only about 60%. I had to modify the brackets, and there was a whole laundry list of things I had to do different.

Things the kit did not include:

Low profile reverse switch

CAG solenoid plug

Harness

Issues with the kit:

Corvette Z06 Shifter box was warped from welding it to the bracket, so I had to send it off to be machined square. It was also mounted on the modified Z06 torque tube in the wrong place.

Transmission brackets left too much margin for error for installation

The torque tube bearings that were installed were low RPM bearings, and also installed with a punch, denting the seal. I removed the bearings and found the torque tube full of metal shavings and grit from the process to shorten and modify it for the 928. It’s a good thing I dismantled the torque tube or I would have had bearing failure in a very short time. Others that purchased the 6 speed conversion or had it installed by the shop that made them had failures within 2000 miles.

Things to keep in mind:

Corvette shifter box comes with cheap plastic bushings

Corvette shifters box is small enough to fit into the shifter hole in the 928 tunnel, only if it is mounted on the torque tube in the correct place, but most of the shifters are not. Cut the hole large enough for the larger aftermarket shifters as well, as access to the front bushing and the rear adjustment screw.

Corvette shifter levers are different than the 928 shifter levers. If you want to keep a factory 928 shifter, keep that in mind during your planning.
