Darn,
I must have been the lucky one on here. When I had my Cobra I used an aluminum Koolflow high volume water pump and billet March pulleys. The only one that didn't line up was the one on the water pump. I called March and told them about it and they asked which water pump number I had and sent me a new pulley and it lined up perfect. That was in 1996 and they are still on their today and have turned many a high RPM runs and a lot of just cruising.
