I have a 39WL I am trying to get fixed up and back together. Wondering if there are any parts breakdowns available for the springer front end and other parts of the bike. I have purchased the engine overhaul manual, but would like more.

 

Bruce Palmer III two volume book is the gold standard for information, make sure you get the current edition not the old one.

Harley once reprinted the parts manual for 1930 to 1949. It may be still available from some sources.

 

Original HD parts books pop up on the Bay every once in a while. I scored a 1946 one a couple of months ago, great for reference.

I bought from them, some years ago, service parts catalog for WLA
Hope they are still in business
