If your engine is a '55 first series or earlier you need the water pump for that engine. If it is a '55 2nd or later engine you need a pump for that engine which has been shortened. If you are using that one you already have the right pulley and you don't need to pay the ridiculous price they ask for a "short shaft water pump". You can buy a stock one from flaps, press the pulley mount to where you need it and cut off the excess yourself.

Post your block casting numbers.
