Hey Kendal, welcome back! The Curt Platform Rack item # C18085-FB has a 1-1/4" vertical tube. The Short Arm item # C32WR and the Long Arm item # C67HR are the replacements for it.
What brand and model bike rack do you have? If you can put that information below where it says Add Comment, I can look and see if we have a replacement arm for it.
