Difficult to access bolts with bar and gear just above two front bolt holes. Fit same hole pattern fine. Old model I replaced had space in front of bar and gear to easily access two front bolts with socket. This one I had to fish an open end into a tight spot, with trailer brace hindering access, to tighten them because the bar and gear are just over the front two bolts. Three bolts and washers included but no lock washers included. Seems like a solid winch so far. Only paid $20.60 new so I'm not complaining.
