Are they the same?? I think they are, but want to make sure!!

I chipped the edges on my 95 pulley trying to get it off.
I found a 94 pulley for cheap.

 

They should be the same (as long as both are from an f-body).

 

Check to see if GM added any weights onto your existing pulley; they'd be pressed into the holes around the perimeter of the pulley. You want to match the replacement pulley to the original one. Transfer or remove weights as necessary.
