waterpump interchange

[574door]

Hi guys. Today is my first day of ownership of a 1957 Buick Super 4-door 4S. I believe it has a 364 since thats the only engine option I have seen for this car. the waterpump is shot and i need a new one. Here's my problem:
Napa's listing on a waterpump for a 364 only goes back to '59. Will a pump for a '57 364 swap with a '59 364? Is it possible that my car doesnt even have a 364?
The casting # on the pump is 1491
1220-1

Thanks a lot in advance for any help. -matt

Try classicbuicks.net where you can't ever talk to a human being. Or try Northwest Speed Equipment and ask for Marty. Phone # 503.697.0500.

Give Buick World a Try. Ask for Jim. They have always done alright by me. They will bend over backwards to help you out. Call first thing in the AM Pacific time. Quality stuff.

thanks for the replies guys. The 59- pump has a longer shaft, so i know that won't work. Autozone has a listing huh, ill have to try that, i guess i can buy a part from the AZ as a last resort haha
