fordguyhey Posted February 3, 2010 Share Posted February 3, 2010 I was curious if anyone has ever seen a B model cab put on an R model frame? I'm in the process of making my B75 tandem and I've picked up an R model for all the donor parts. People keep telling me I should just put the B model cab on the R model frame that is already tandem. I haven't done any measuring yet, but I'm really curious if it's even possible without tons of fabrication. Me personally, I would rather keep the B model frame under the B model, just wondering what everybody else thinks. Quote Link to comment Share on other sites More sharing options...

fordguyhey Posted February 3, 2010 Author Share Posted February 3, 2010 (edited) Does anyone have any pictures or info on the B to R model conversions? Edited February 4, 2010 by RC B75T Quote Link to comment Share on other sites More sharing options...
Rob Posted February 3, 2010 Share Posted February 3, 2010 I have seen it done but did not take any measurements. I know some of the cab mounts were fabricated and not original to either a B, or R model truck.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

fordguyhey Posted February 4, 2010 Author Share Posted February 4, 2010 The only way I would ever do this is if it would come out looking like it was supposed to be that way. I guess I'll have to do some homework and see how well it will work. Otherwise I will be stretching my frame. Quote Link to comment Share on other sites More sharing options...

The only B models I've heard of on R model frames are short nose trucks like B61 style. The B75 is like 9 inches longer in the nose so I'm going to be doing some careful measuring this weekend.

fordguyhey Posted February 9, 2010 Author Share Posted February 9, 2010 after some measuring, it looks like the biggest problem I'm going to have to deal with is that the R model front axle is like 6 inches wider than the b model. So I guess my tires might stick out of the fenders a little bit. Quote Link to comment Share on other sites More sharing options...

If I remember correctly the 72 R model I have has the same measurement as a B61.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.
