My 1929-46 Chevrolet Master Parts Price List shows the same part numbers are used for the L and R doors to 1939-46 truck cabs. They should fit according to the part data I think. Other Bolters with more knowledge may pop in and offer more details to answer your question.
Are you posting your question in the "Big Bolts" forum because your truck is a "Big Bolt"??? Your other posts asking questions about cabs and such are found in several other forums, so just looking to maybe better define what truck you have and are working on?
