Wow bro, good idea and good work 👍I've been working on the R&D on 5 speed "T5" swaps in C4 corvettes for a few months now, and working with a company called Pro Street Customs who has designed a CBEAM adapter bracket based on my specifications. This bracket will be available by the end of next week for purchase for about $175 / shipped.
The specifics are:
1) A T5 transmission uses the same 4+3 bellhousing/clutch/driveshaft
2) A T5 bolted to a 4+3 bellhousing is the same length as a 700R4, making auto-stick swaps cost effective now
3) You do not need to modify the CBEAM, just use the adapter
4) The shifter can be modified to be offset and line up with the shifter plate
5) T5 transmissions average used cost is about $250
I've been working on a writeup for the swap. Some of the part #'s listed in the writeup are wrong, but within about a week or so the writeup will be 100% correct.
