I have a 99 mustang, so do i have a long water pump. In the foot notes in summit racing, it says that it will not fit the short water pump. It runs about $345 in summit; is there anywhere else it could be cheaper.[/align][/align]

 

You have the long one. The mid 01 model year went to the new style. Steeda has a good write-up on their site concerning it.
