Bought a bike off craigs list, one of the upper right water pump mounting bolts was rung off they had broke the casing behind the pump. So i had it welded but the guy had no measurement to go by, so when i put it back together the casing that he had welded wasnt the right distance from the block and caused the water pump to be out of allignment, and broke the end of the water pump shaft off in my block. So i need to know the measurement, how far the stud sticks out of the block on the top right water pump mounting bolt if anyone has a spare casing and dont mind measuring it im in need of your help let me know how you measure it so i can measure mine the same way. I appreciate any help please...really want to ride this summer and so far no good.
