Looks good.

My dart's trans was rebuilt in the mid 80s it had a flat rear seal like in the photo post 29.

It was leaking so I replaced it with the bellows type.

Unfortunately the seal is just long enough that the bellows end touches the up curve of the yoke more than I would like. But at 1000 to 2000 miles per year I suspect it will last my lifetime

I would’ve preferred the seal with the boot. However, the OD of the seal would’ve been too large for the tail shaft housing bore

The 8835S (both the National and Timken part number) along with ATP TO15 are booted seals with the 2.254" OD. Simple parts-store stuff.

Unfortunately my local parts store did not have them in stock. I’ll write that down for future use though

My trans went 175,000 miles with the flat seal, I think you will be fine!
