Yes it'* possible.
You sure it wasn't a 4T60E-HD? I know they had those but with special parts to where you couldn't just swap the diff from the 4T60E-HD to the 4T60E. I know for a fact this was the case for the Riviera for that year.

I recommend that you DO NOT bolt a 4T60E to an L67. I had that option with my L67 swap in my 95 Regal and I opted to get a 4T65E. There have been numerous reports of stretched chains in 4T60E'* bolted to L67'*. The transmission cannot handle the power very well due to that stretched chain. You might get a few thousand miles out of it, but I'd be surprised.
My personal plan of action was to get a 4T65E from a 3100 powered car and bolt the HD differential to it, which will by next week will give it 3.29 gears. Easier on the transmission, and more power to the wheels.
