I think the only issue would be the single mount point at the rear of the '47-48 cab/frame. But that can be dealt with by drilling holes for the later rear cab mount shackles in the web on the frame rails. Let me know if you need locations for the holes. My '51 frame is accessible to make measurements if needed.

Here's some info from Brad Allen's Flickr collection.

If you're smart enough to take it apart, you darn well better be smart enough to put it back together.
