Had to replace the starter in my 95 s/c today. Turns out that the only '95 in my local salvage yards is now gone. So I had to do some quick research. What follows are all of the cars you can pull a starter from for your '95 Riv w/ Supercharger:
'97 Bonneville (3.8 /w Supercharger)
'98-01 Bonneville (3.8 /w Supercharger)
'95-'97 Camaro (3.8L)
'96 Cutlass (3.8L)
'97-'99 Eighty Eight (3.8L /w Supercharger)
'95-'97 Firebird (3.8L)
'97 Grand Prix (3.8L)
'98-01' Grand Prix (3.8L /w Supercharger)
'96 Grand Prix (3.4L)
'96-'97 Lumina (3.4L)
'96-'97 Monte Carlo (3.4L)
'97-'01 Park Avenue (3.8 /w Supercharger)
'97-'03 Regal (3.8L /w Supercharger)
Hope someone finds this useful.
