This type of parts book is frequently listed on ebay and is a good source for part #'s. http://www.ebay.com/itm/1946-1958-19...item1e6d430e58
Always read the auction descriptions carefully so you know what you are buying.

While the book listed above states that it covers the years your looking for, that's not always the case. You should look to a book closer to your own year as well. The later years MIGHT list a different part number that superscedes the original.
I've found this site helpful if you have the patience.

Yes, you should listen to the literature master. I agree that it's a little frustrating trying to accurately ID Old parts with newer #'s, but so far an age appropriate book has eluded me. I probably just need to try harder.
