Source for cover zipper?

[4S50]

The cover zipper on my Mombasa RTT has given up the ghost. I ordered one from Mombasa and they only sent the top, cover, zipper. I found that Tepui has a replacement that appears to have both halves, but they are eternallly on back order. Does anyone have a source?

Might be a good excuse to buy a replacement cover depending on the condition of the current one.

I called Mombasa a few ago and they do have the tent platform/bottom zipper with the welting (or whatever that is called that fits in the base groove) and is sending it to me. Easy folks to deal with!
I thought about buying a new cover, but in the pictures they only show half of the zipper. My cover has earned a few scars but is still good, zipper though is shot.
