I never could find any after market. I made my own new top pin, and turned the bottonm pins down and pressed hitch pin bushings over them and then turned the bushings down to the size I needed down. This gave me a better fit since the nonreplacable parts were also worn some. You can get hitch pin bushings at any farm store. (TSC, Rural King) This is easy if you have access to a lathe. Total cost was about 10.00. Through BC the lower pins were 35.00 ea. Don't know what the top pin cost. Hope ths was some help.
