Harleybullet,
I remember when you got the winch bumper a few years ago in a mass buy.
There are basically two kinds of 4 hole winch attachment patterns. One is for the consumer winch with a not-so-wide fairlead and tall, narrow drum. This is what most people on here have. Then there is the commercial winch carrier. Much more rare. Sturdier with a wider 4-hole pattern with a wider mouth at the fairlead (rollers). It helps keep the amount of winds fewer and hence more pulling power. I bought one of these by mistake from Warn and it still languishes out behind the shed.
Alex made his own for his 17,500 pound capy winch. This one is not going to fall off and adds the least amount of weight to the front as there is no winch bumper. D-ring holes, yes. Powder coated: yes. This is the narrow drum design.
Attached to frame rails sturdily. Warn uses a wide drum on their high capacity commercial winches. So, measure the holes, if any, in your winch bumper and make an accurate card stock template for comparing to winches that are in the running. One last thing. The commonly held belief with off-roaders is the winch capacity should be at least 1.5 times the weight of the vehicle. For me, @10K pounds, a 15K pound winch is enough. Yet another thing. Some winches attach the 4 holes to the front plate, some to the base plate. The front plate attachment is the sturdiest.
I've seen some 18,600 pound capacity Chinese winches of late and if you can put up with the snails pace speed, it should be enough overage to tackle anything you might pull against.
