The Bulldog Coupler Repair Kit BD0287740300 is designed for a round coupler so if you have a square tube you'll have better luck with the Gooseneck Coupler Head Kit # GC-HEAD. This is designed around etrailer and RAM round and square gooseneck couplers but since it's a weld-on installation you shouldn't have any issues getting this installed.
