Question:

Are the following parts all compatible with each other? I am mostly concerned about the snapper coupler pin that will hold the ball mount into the trailer hitch. Please let me know if I need a bigger pin. Thank you. C45042, 19258, and 37201051.

Yes, I can confirm that all of those parts do fit together. The Coupler Pin - 5/16" x 2-1/2" item # 37201051 will be loose inside that ball mount though. You will get quite a bit of play. The hole in the Curt Class III Ball Mount with 2-5/16" Ball - 2" Rise or 4" Drop - 7,500 lbs item # C45042 accepts a 5/8" pin. I recommend purchasing a Curt Trailer Hitch Receiver Lock - 2" Hitches - Chrome item # C72KR. This will secure your ball mount inside your hitches receiver and keep it from being stolen.
