When I bought the 1350 to use for the doubler, it came with the linkage for the AL4D which is supposed to work with the M50D setup. I’m here to tell you it doesn’t, the upper portion of the linkage hits the back of the transmission in high range. So out came the welder and the chop saw!
It wound up sitting right where the stock linkage would sit, so I might try to find the stock bezels to seal that up some. Right now, I just have the carpet laying over the hole in the floor which I don’t think is going to be a good permanent solution.
