Advice please. Removing bi-fold bus door replacing with caravan door

Hi all!

Wonder if anyone has attempted and succeeded in replacing a bus bi-fold door with a caravan door and frame?

I have a Ford Iveco mini bus that I'm(slowly) converting to a motorhome. I'm using most of the interior and electrics etc from my previous Ford camper. With a few adjustments here and there its coming together quite well.

The time has come to tackle removing the bi-fold door and replacing it with a caravan door and frame.

I would very much appreciate advice from anyone who has successfully done this or might have the general expertise as a fabricator.

Hope someone can help.

Many thanks

Billy
