Thanks for reading along! I can go into a lot more depth here and I agree it's much better to have the explanations and string of photos than just a single photo with a short caption! The template was very helpful because it gave me confidence that I'd have the right cut and I spent almost no time iterating.

Continuing with the update....

One thing I noticed when my transmission parts arrived is that the transmission crossmember was a different design than what I had seen Silver Sport use on another Nova. I called and confirmed they had recently implemented a more universal/adjustable version. Unfortunately this new version was not a good fit - the mounting area of the crossmember was several inches lower than their original design and blocked exhaust routing.



A quick phone call and Silver Sport offered to rush ship a new crossmember using their older application-specific design. This gained a few inches of clearance which was plenty for my 3" exhaust routing.






Next, I installed the STX short throw shifter. This included a bronze bushing to replace the factory plastic one in the shift rail. I used Loctite bearing retainer to keep it in place.



At this point I decided to reinstall my driver's seat and mock up shift lever options. Knob position and lever length affect driver's arm position, reach, and throw, so I think this is an important thing to get right for the specific car, driver, and seat position. For mockup, I used vice grips, some flat bar, a long bolt, and a shift knob. This allowed me to shift through all the gears and choose what worked best for me. It's worth noting I am 6' tall with a 32in inseam.






The 8in levers were comfortable, but the length and longer throw made it feel more like a semi truck compared with the throw and height of the 6in levers. In spite of the shifter being 3" further back with the Magnum-F trans, I still found the straight levers resulted in extended reach in forward shifter positions. With the laid back levers, my elbow was just slightly bent for comfort and overall I preferred the 6in laid back shifter over the other options. So I shopped around for a lever and found I really liked the Hurst billet levers that were released last year.



I highly recommend mocking up parts like this or trying other people's cars, because it makes a bigger difference than I previously realized. Fitting the car to my personal ergonomic needs has made it a lot more enjoyable. That was true when I lowered my seat height, adjusted my shoulder harness tether length, and now with the shifter position. The car is a joy to drive.
