No problem with duplicate postings. Our knowledge of the 40s cars is a little weak down here (wish that would change), so cruising the AACA General and Tech forums may help you along. The BCA and Cadillac forums are another option since they do share some Fisher Body stuff with the Oldsmobile. So between OCA, AACA, BCA and Cad/LaSalle, you could easily spend a few hours with us!
I'd recommend joining the National Antique Olds Club too. They are probably the best source for pre-war Olds information.
naoc@sbcglobal.net Please tell them you got the lead from the AACA/OCA online forum.
The
Standard Catalog of Oldsmobile shows that 1940 cars can be identified by the body style number. Series 60 are 35, Series 70 are 36 and Series 90 are 39. Since it's a six-cylinder, it will be either a 60 or 70 series car.
