I purchased a 4 inch riser from power madd for my 05 rmk 50th anniversary. Unfortunately, the one that I recieved didn't fit. It had a cross section of 2 inches by 4 inches. My sled has a cross section of 2 inches by 3 inces for the riser mount. Does any one have a recommendation and a part number for a 4 inch bar riser that will work on this sled? Last resort is that I will build one myself.
