Hello new user with a few questions

[BDA]

FYI in case it's useful, the 5th gear is under the end cover. You don't have to crack the case open to get to it. Also it looks like there is a separate front shift link for the TC and TC Federal from the TCS and TCS Federal. Not sure why...

I have a 365 for my TCS and it is totally locked up. No telling how bad mine is inside. I am interested in your project and look forward to the results.

do you think this application would need a ground gear? Or could you get away with a hobbed and hardened gear?

To be honest I design and spec the darn things, but I am no expert in how they are manufactured. I assume car xmission gears are hobbed because it is cheap and hardened because they have a long and difficult wear requirement. Hard to tell without having one to look at.

I recently bought a 365 gearbox to swap for the 352 in my TCS, but I am hoping it will go in and work perfectly without me having to crack the case open. Fingers crossed. If not I guess I will have a Hewland 5th gear to reverse engineer and replace.
