If you don't have one already, a factory shop manual, as well as a Motor's Manual, is a very wise investment. The Motor's Manual has repair advice that isn't found in the factory manual. These books are available on eBay and from other sources. The factory issued shop manuals covering several years at a time (1946-51, 1946-52, etc) The '46-54 book has been reprinted and is available from several vendors. I'd try to find an original '46-'52 shop manual if I were you, because the body section of the manual covers the newest year that the manual covers (in addition, the clutch linkage changed from '51-'52). I've also heard that the reprints have fuzzy pictures but haven't seen one to verify.
Don't forget to check 'everyday' parts suppliers like NAPA and rockauto.com because there is still a huge amount of mechanical parts available from them at better prices than the 'collector' vendors.
Hope this helps.
