I did try the 944 shift rod first but it rubbed so I ordered a 968 one. Then I tried the 944 shift lever and it wouldn't mount up to the 968 shift rod so i order that lol.
I would definitely say what I did was the least invasive and required the least amount of parts ordering.
To help answer V2's questions -
1. The 968 half shafts are different lengths - I would NOT try them in a car with a 944 trans.
2. The 2 bolts on the top of the trans mated perfectly as well. So I am not sure about the crossmember and gas tank being different?

I kept the 951 Torque tube and bell housing - the trans looks like it won't mate up but it will I measured the bolt spacing before I tried to install it
For me, since it is a dedicated race car - I found myself being at the top of a gear as I approached a corner but well before my braking points. So I had to either hold the throttle to maintain the RPM or short shift. The closer gear ratios should allow me to stay in the optimal power band more of the time without having to make such decisions about short shifting or not.
I have a 2 post lift and can tell you the book time is a liar - maybe for a newbie but really I would say...6-8 hours?
I answered part of this above and the first test day is on the 30th so cannot speak to some of your questions. I am prepared to do more rowing but should be 2-3 seconds faster per lap I think - based on feedback from others with a lot of experience with these cars. Yes, the trans is stronger. I race in GTS3 in NASA and V5 in POC and haven't figured where I will land in PCA - GT something. I make about 250 rwhp and weigh about 2850. The ability to handle more power was not my main concern but is an added bonus. It was mainly how often I found myself having to short shift or hold the throttle. The *theory* is that I will be able to stay in the power band more often and be faster out of the corner. We will see and I will report back.

Measure them. Understand we were also stumped, till measuring the difference from the 968 transmission as installed in a 951 vs. the OE five speed. The only reason we had issues was from 1000WT axles from the Drive Shaft Shop. These don't have the same side to side flex.
It's minimal, but relevant.
