It's me again. Was the fan and pulley set-up on the 289 Cobras, the one that was bolted to the water pump and was supposed to be removed after the break in period, the same as what was on a U code Mustang? I know that the fan was the same as the 64 six cylinder Falcon, but, it seems like that would just about have to be the same as the U code Mustangs. I have no idea which pulley was used. Stamped steel? Cast iron? Thanks.
