a/c clutch???

We just found out that our a/c clutch is melting away and we obviously need to replace it. The mech. shop said that if we can just get the clutch that is probably all we need, but I can't seem to find it alone. I can only find it with the compressor. Does anyone out there have any knowledge on this?

what year and model ??????????

it is a 95 4 cylinder.
