Hey guys. Got a problem here than even a BFH won't solve.

Now I'm a pretty good mechanic and fabricator, and maybe I just had a few too many drinks after work today, but this project is gonna meet up with my welder real soon unless y'all have any ideas.
Titan ballast box, TerraKing quick hitch bushing kit. These roll pins are the toughest I've ever come across. They fit into the bushings easy enough but only make it about halfway thru the Cat 1 pins on the ballast box before they start mushrooming. Any suggestions other than buy straight Cat 2 pins for the box? If that's the case, I'll just weld these QH bushings on and be done with it.
