1989 R3500 Hitch recommendation

[atup1996]

Looking for a hitch for my 1989 GMC r3500 cab and chassis truck. Originally I purchased a B&W class 5 hitch HDRH25122. But it wont work. It hits the shackle mount on the frame. Anyone have this issue? What hitch are y’all running on your cab and chassis squares?

I bought a nice class 5 on etrailer.com. I can't remember the brand but I wanted the B&W and settled for the cheaper one. It's still a beefy beast. I don't know if there is something unique about the 89 r3500 though. etrailer.com has the best selection at the best prices.
