Never have done it, but it shouldn't be too bad of a project. I think if you were to cut the back of a big window cab apart at the seams, you should be able to do the same with the small window cab to put it in. When you cut the back out of the keeper cab, you should build some good supports to hold the roof and the side of the cab in place so aligning everything on the cab doesn't turn into a nightmare..... If taking it apart at the seams won't work, then cut about 3" outside of the big window, flange the cut line, and cut the small cab back window out and put the big back in. Use a hard paper or cardboard pattern to make your cuts and remember that the opening on the small cab will have to be 1/2" smaller all the way around to lay on the flange you made on the big back window cab section you cut out!!!!
