probably need a bit more info...
in your scenario a 95 normally aspirated engine would be a series 2 a 95 supercharged engine would be a series 1.
in 96 sc engines were series 2.
a balancer from a 95 normally aspirated series 2 engine is of no use on a 96 or newer sc engine since it does not drive 2 belts - it wouldnt run the sc which has a dedicated belt that runs it via idler and a tensioner
so if you are working with a series 2 supercharged engine any balancer off a series 2 supercharged engine should be compatible from what I know 96-04 and likely one from a series 3sc (L32) is probably compatible also
if you are in need of a balancer let me know I may have what you need
