Hello Timothy, thanks for reaching out. What part are you needing exactly? Are you needing the wheel center cap? Or are you needing the grease cap that goes on your hub. I see you have a 5,200 lb axle an typically this would use a 2.44" grease cap like part # RG04-080.

If there is something different you are needing just let me know.
