    I’m preparing my Z for the new radiator/electric fan set up and don’t think I can re use these bolts haha. Anyone have an idea what size I need and is this pulley reusable? I don’t see why not just want to make sure. Also, would anyone be kind enough to post a diagram or pictures of their LT1 non smog pump belt setup? Thanks !!

    Put some short studs in the water pump flange. Should be able to get the right ones at a good parts store. Then just use nuts and lock washers.

    Just get same bolt thread, hex head with lock washers at about 3/4 to 1" long. as for the belt set up you'll need to measure for your pulley config.

    I put a used 97 Buick dual speeds cooling fan on my Camaro. Cools great. Cheap too was $5 at the swap meet.

    The balancer is just an aluminum 2 groove generic summit one. The water pump is an aluminum 2 groove generic paw one.
