Your probably right, but yet I've ran into another problem. I thought I had all the parts to do the water pump aswell but it seems like I have the wrong impeller? It just flops on the shaft which isn't doing me any good. Anyone know if the 250 stuff will work? Or can someone snag a pic of the 500 impeller for me? I have all the clutch internals in and now just need the right impeller and new gaskets for stator and clutch cover. Thanks for the help guys.
