All you need to do is replace the subframe to get it to fit either your 149 or 1200. Others may be interested in your narrow frame subframe. Everything else about the blade is interchangeable.
I sometimes make my own lift rods from 1/2 inch steel rod, bending it with a torch. there were various lengths, IIRC, not sure what exact length the 149 used. Somebody here has previously posted the various lengths and which tractors they fit.
