I'm having my mechanic install a correct 608 replacement rebuilt water pump (however the date code is from late 1966) on my LT1. The pump that's being replaced wasn't correct and was leaking badly. Once the pump was installed he attempted to attach the water pump pulley (correct 3848904) but the pulley is rubbing against the pump. Any ideas what the problem might be? Should there be some kind of spacer between the pump and the pulley? Help!!
Thanks.
Thanks.
