!) I have a set of engine mounts from a 250 and 200. These are the metal type attached to the block. One set shows L 250 and R 250. The other set is not stamped and came from a 200. I cannot see any difference between the 2 sets or left or right or 200 versus 250. Are these the same parts? 2) I have a set of frame mounts off of a Maverick. Are the 250 and 200 frame mounts the same?
