In Reply to: Model A frame posted by Jeff ernsberger on September 23, 2007 at 20:49:50:
It is in the area of the drivers front door post and close to where the left rear motor mount goes to the frame. it is on top the frame. The engine number is on the drivers side of the engine above the water outlet. If you are lucky they will match on all the digits. The frame numbers are often very hard to see. Clean the area as much as possible. There is nothing to decode as in modern numbers. There ar published lists by months of manufacture. check out national club websites for MAFCA.com, modelaford.org, and MAFFI for more information.
