Problems Putting in the selector shaft seal

man, I can't remember where I recently saw it, but there is a tool for removing and installing the seal in the car. Probably Lisle, or KD, or OTC. Maybe someone else has seen it, or has it.

I still have one of the tools for a GM350 and 400 from a past life, but not one for Chrysler.
You can get them on Ebay, and this is the one for 904/727.
