Erix Yours is a noble task, but it is one that people can find for the Ford and GM cars, I found two manuals on fords from 1932 to 1941, and from 1942 to 1948 that said they had all the frame diagrams for each year.
The reason I answered like I did, is I'm a street rodder, I don't think about restoring a car when someone would ask about two frames, I don't think about points because the frame isn't spot on, street rodders build the frames they need or rebuild them to fit their needs. But if you are into restoring cars, I would bet if you went to a Ford or GM forum, not that I want you to leave here, but if you would ask that on a genie forum, you would have an answer pretty quick. I tried to call a friend of mine that has 3 41 fords he restored and I'm sure he could tell you more about the frame than I, but no answer. I called a couple of guys in our club that are Ford guys like me, they answered like I did. So it is all in who you ask. If it were me and you wanted to make a list of frames with dimensions I would do anything but Ford or GM. Hudson's would be a good one, They had the Essex, Terraplane. there were a lot of different cars made back then, most would be hard to find info. on.
I just think you asked the right question in the wrong place. I'm sure there are people on here that would have what you want, but most of us are street rodders and we look at a frame as weather it will flex when we but a blown Hemi in it, not if it is the exact frame for that car. our points count on the drag strip not at a show, when we go to a show, they judge the frame on how nice it is built and how nice it looks, no more, no less. Good luck again yours is a noble effort, you will gain a lot of knowledge on different cars. This is JMHO. :mwink:
