I put on put an aftermarket harmonic balancer for a 351. I put the factory 5.0 crank pulley on and the factory 5.0 water pump and water pump pulley. I was told I could reuse both factory pullies. Car is a 93. The crank pulley and the water pump pulley are touching. They are rubbing together and I cannot put a belt on it or anything. Do I need a different pulley? I'm not sure why they are touching. What do you think? Thanks for the help.
