On a side note, it's been a few years since I changed the fluid, so I can't really remember if I did it, but it probably would be a good idea to coat the threads of a new bolt with anti-seize.

There is a generic part available for the GM tranny drain that is steel and less likely to strip (ie is a normal bolt instead of an hex key). No solution for the fill though and I'm in the same boat. If you can estimate correctly, the dip stick plug sits along the top edge by the exhaust (passenger side). It's a two-stage pull plug (in a strange way sorta like your trunk interior plugs) but comes out pretty easy - I had to fill there in a pinch.
