A833 Overdrive, Bellhousing, Driveshaft, and more

Yeah, apologies if that was confusing. Transmission is great for the car.
However, the stock small block bellhousing that I installed uses the 4.354” input bearing retainer. There are ways to make it work (like buying different input bearing retainer + machining bellhousing, or using a different main case), but I decided to not be that creative during the swap.
