TOPIC: Driveshaft Swap - getting it sealed back up.

Exchanging driveshafts in a 66 Starflite 100. I know you have to crack open the gear case and the snap ring from hell, then make sure you don't cut the shift wire.

My biggest concern is getting it sealed back up. Right now it passes a pressure test but I can't use the existing driveshaft (not propshaft).

And if anyone wants to rent me a snap ring tool feel free to get in touch.
