I was just gassing off there. If it didn't leak when you pulled the shaft out, it won't be leaking now.

Now I'm curious as to what to do with my own driveshaft. The '70 manual doesn't say anything about the spline. The Chilton's for '70-'80 Chevy trucks says don't do it at all. Someone is wrong, but for your truck you have it in writing for your specific year.
