WHY WILL THIS NOT FIT AFTERMARKET BOXES? HOW DO I TELL THE DIFFERENCE OF OEM TO AFTERMARKET?

Part # 91032284 If you order an aftermarket box from Speedway or other suppliers the input shaft is actually .010 over the 5/8” so this coupler will be too small. Careful measuring will determine fit and if you have the larger input we offer part number 91032235.
