In order to get the 8 degree negative angle at the point the sheet enters the winch I need to put a spacer under the winch. The self tailer(not mounted) is on the left of the original winch. I haven't measured the angle yet, but would an 1 1/2 inch high spacer be too much as far as a solid mounting for the winch if I need that much. Or, should I go with an inch high spacer cut to wedge shape in order to tilt the winch away from the sheet to get the correct angle of entry. thanx, gene
