Technically, a cab off a '91 R model would work, but of course your interior would be updated, which may not be a bad thing. Don't the older r models mount up solid to the frame with 4 rubber mounts? At some point, I'm guessing around the late 70's or early 80's, they went to air ride. I don't believe the hood would matter, although when they went to having air to air in front of the radiator, the hood got updated a little bit. I believe around '81 or '82? A power steering pump, resevoir, and a sector shouldn't be too hard to find in a bone yard somewhere.

yup, might have to change the frame cab mounts if you use a 73 and newer cab as they went to the trunion mount instead of the buscuit mount. other than that not much changed other than the hood used rollers to rest on when they had air ride so it would move. might be other little obstacles but not much major.

Ok let me try... Early r 600 models had a small cab (metal dash) and short hood, in 73' they went to the +3 cab giving more rear room. I think in the mid to late 70's when the 300 came out the hood was stretched about 2" to help make room for the inter cooler. The new cabs will bolt on to just about any frame but check the hood size and rear cab mount locations.
