Paul is right, while you got your drill out, put a drain plug in your drive axle. When I had my '95, I used Marc's instructions to do that to mine. Made my life a lot easier when it came to axle lube changes, which I did every 3-years.

As for the block drain, my 95's engine had the big drain. Apparently, that was a change GM made after it discovered problems with debris plugging the smaller hole.
