Don't they also have different crossmembers? And is the gauge thickness of the steel thicker on the heavier trucks? I know there's some differences besides length.
Bottom line is, they are not interchangeable. F1 is it's own unit.

Frame dimension differences?
Yes Ilya you are certainly correct . . . thanks. I was focused on Lukas's original question. But I am interested in 52 Merc's observation about cross members, etc. F-1 to F-2. I'm trying to find a rack and pinion steering gear for my F-2. All the parts guys tell me that theirs won't fit but no one can tell me why. Obviously anything can be made to fit it just depends upon how many modifications need to be done. Has anyone done this or do they know why an R&P gear for an F-1 would not fit an F-2?
Sorry Lucas . . . I don't mean to hijack your thread but it is kind of on topic.

They use the same solid beam axle, same spindles, drag links, etc..., so I don't see why not. Differences are 11" drums for the F1, 12" drums for the F2, plus the wheel bolt pattern. An optioned 9 leaf spring pack vs. the normal 8 leaf spring pack shouldn't make much difference if any. I'd be willing to bet it's their normal "disclaimer".
It looks pretty straight forward to me. He has 8 leaf springs and it looks like he has good clearance but I think that he has a '53 F-1 (see the large rubber stop). A little different than my '50 F-2. To complicate things more I am installing Posie Dual-Flex springs on the front which will give me a 2-3" drop. I'll have to do some measuring tomorrow . . . providing the heat takes a break. It was 97 deg here today !!!

Yes, Wayne, to be specifically correct, which I should have been, the F2-F3 frames do have different xmembers than the F1 frame. The transmission xmember is different, as well as there's at least one or two more xmembers because of the length. I don't believe that the gauge thickness of the steel in the frame was different. I believe that it began to change with the F4 model.
