Dave, thanks for your response. Here's the story and thought process. My wife found this truck and wanted it. I ASSUMED it was the same as a Ford so bought it for her. (my mistake) Now I find that in fact the 46 and 47 Mercury trucks, made in Canada, are actually different than the Ford from the windshield forward. From 48 forward they are all Ford with different badging. I can't find any frame drawings for the 46 and am working with Heidt's for front and rear suspension. They have never done anything for the 43 to 47 model years so we are looking to see which years had the same chassis. They have from 29 to 42, then nothing until 48. The war years are so rare that I can't find ANY parts. Consequently I'm looking for any help I can get. We are also looking at the possibility that 42 may be the same as the 46.
Sheet metal is also another big problem. I may have to just make everything from scratch. ??? What you stated is correct regarding engine and front frame extension to the bumper. Thanks again, Jan
