I was installing a set of after market pullyes on a 1966 289 mustang. They did not line up. Italked with friend of mine at our local NAPA store he sent me to Lindseys automotive in round Hill ky they can rebuild your water pump and install different length shafts. Fixed my problem and all works well and a very resonable price. Just thought I would put out there in case anyone runs into the same problem it saved me alot of work and money.
