Have a chat with these guys James.... http://www.towbarexpress.co.uk/?gcli...FVVu4wodgHflNA

They will come to you and I'm sure they can fit somethng. You May struggle to get the military type if you want it easily removeable and swappable with a ball, but I'm sure they will tellyou.

Have a look at the Westfalia or Witter removeable bars. They are very good and the support bar is usually hidden away.

Cheers
