Linhof and Polaroid

I got lucky and picked up a mint Linhof Master Technika. Because of work, I won't be able to actually get to using the camera for a week or so. I'd like to start off shooting Polaroids with it so I need to know what kind of Polaroid back that I need. Just a regular 4x5 back or some other kind? I think I saw a few 545is on eBay, do they work?

Thanks in advance.

The 545 type backs work with 4x5" Polaroid sheet film. Unless you have a supply of this film on hand, it would make more sense to invest in a 4x5" packfilm holder like the Fuji PA-45, which works with Fuji instant film that is still in production.

Thanks - exactly what I was wanting to know.
