You probably got the 1/4 pins looking at the picture and need the 5/32. Go to a hardware story they usually have them or an RV dealer for sure. Isn't fun to have a Trailer with all the excitement what goes with it.
I am installing R12 insulation in the underbelly and shaking my head the shottie work I see. Wires and heating duct rubbing on the metal cross members. No wonder it is so much fun to have a TT. Good luck with the pins.
