Posting pictures for Cummins12V98: pin box bike rack receiver for TrailAir
"In the third pic it looks like the device I made is not at a right angle to the top of the pin box but it is.
The top and sides are 1/4" X 3.5" flat bar the receiver tube is 2" X 2" square tube 1/4" wall. The back piece is 1/4" X 2" bar. The bolts are 1/2" grade 8 1 1/4" long. I ground down the two bolts closest to the air bag on each side so the bolt was the same length as the nut for clearance. The vertical dimension of the side PC along the front edge is 6 3/4". The top, sides and back are all separate pieces. I welded the outer corners and then ground a radius on the outer two edges.
I did have to cut off the end of the part that goes into the receiver. This is because the depth is only 3.25". The reason I did not use 4" or wider bar is because I still need to be able to get to the air fill valve for the air bag fill.
I bought Masterlocks keyed alike for the bikes and my hitch. It was a fun project, I may have $20 in parts and paint. Feel free to copy if you want.
Any questions just ask.
