I used a 95 sbc 350 truck set up on my Olds but ran into problems. The driver's side two bolts line up but the bottom attachment point needs to be removed. The biggest problem is the passenger side, only ONE bolt lines up with the head. You need a custom bracket to go behind(needs spaced out anyways) that would allow at least two points attached to the bracket AND to the head. If you use the RWD Olds 4.3 V6 diesel water pump that is reverse rotation, the water pump pulley WILL bolt right on. The bottom pulley needs ground down to clear the top pulley. The bottom pulley also needs a much larger center hole and Olds bolt pattern drilled. Yes, Olds belt set up is far from simple.
