Thank you Dennis-

Perhaps I should back up- I have never seen the three point mount system, so I have no idea what you're talking about. Where is the "center" mount? In front or back? Could someone at least describe what it looks like? Does the early 49 frame have a different cross member setup, or is it just differences in the holes?

Is drilling the frame for the center mount preferable to drilling holes in the cab for the four point mount?
