the diff in the back , the early has a shallow indent[ about 1/2 deep] and 3 ribs about 8 inches wide in the back, the later has deeper indent and 4 ribs in the back. [about 3/4 inch deep] the cab buck at the museum has both types carved in the back. the frame had a cross member with out the V channel going back to over axle.

Note the difference in the front frame crossmember too.

Loren Hoekema has told me about the early differences in the 1949 trucks, especially the back of the cab and center crossmember. This is the first time I've seen the differences illustrated.

Loren is doing research on the very early '49s to document changes to the 2R series made at the factory during 1948. I told him that was a big assignment he had chosen for himself. Of course, it was during this same time frame that some M series features were replaced with true 2R pieces in the early 2R trucks. It really was a transitional time rather than a clean break with the prior series as most new models enjoy.

My truck was made in October of '49. It has the "K" front engine support set up, but I never checked the back of the cab! It does have lever shocks still as opposed to tube, which I know was another running change.

After having my 2 2R's for about 10 years and being pretty familiar with about every part of them, it is nice to know there are still interesting things to learn about 2R's.

I do believe the lever shocks were still the standard shock for the heavier trucks up well past the 2R's. I think the "airplane" shocks were just an option during at least the earlier years of the 2R's and wasn't just a switch at the factory at some point. Not sure when they finally gave up on the lever shocks for the lighter duty trucks. Maybe somebody can lend some insight on that topic in a new thread.

BTW, my Oct. '49 2R15 has the lever shocks and my '53 2R11 has the "airplane" or tube type. I don't recall offhand on the production orders for the trucks whether they were listed as options of not. Both trucks apparently have the later cabs and the frames have the K member up front.

My '49, s/n R15-9188, built 5/5/49, has a cab with four ribs (cab #70738) and the angled motor mount rails.

My 49 2r10 with assembly date of Jan 19 1949 has the old style frame and the 4 rib cab.
