Light seals on 645?

Lots of film bodies, a couple of digital ones, too many lenses (mainly older glass) and a Horseman LE 5x4.

I'm awaiting delivery of a 645 (original version) in apparently near-perfect condition. From what I can gather, the film back has a light seal, but I can't find any information on replacement seal kits. I'll check it when it arrives but, is this the only light seal on the camera, and if it's in poor condition, where can I get a replacement?
Thanks
