Does anyone know where I can find a replacement film plane for this?

I'm not sure what you mean. If you mean the pressure plate, I have seen this on ebay http://www.ebay.com/itm/Free-Shippi...535?pt=LH_DefaultDomain_0&hash=item1c4ae223a7 and there used to be another listed a couple of weeks ago. I searched by "mamiya six."
EDIT: I don't know what if any effect the marks on the flat springs night have.

That's the piece. Thank you. The flat springs press against the film mask, this camera focuses by moving the film plane, so there has to be some tension against the pressure plate.
You can see what I mean in the second image on this page

You could also contact Jurgen at http://www.certo6.com and see if he has any spare parts.

That's the one....
That's the one....
Those marks on the silver/chrome springs do not touch the film. They ride on the portion of the piece that the film rides over, and above the film, pressing the film flatly against the focus part that moves in and out.
That is why the Mamiya SIX folder is noted as one of the flatest film plane mechanisms in that era of camera's. Those camera's were made from late forties to mid fifties (1956?) and that piece remained unchanged as I recall.
I would check with those people who restore these camera's .... Cupog, Certo6, others. Then I would simply keep my eye out for a clapped out Mamiya SIX up through the Automat SIX of 1956. You'll turn one up.
You could make one, if you know how they work. The springs simply hold the flat plane above the film and tight on the film plane rails as that whole mechanism moves back and forth for focus.

I know the springs do not touch the film, and not even the paper backing, but rather press against the rails shown in the photo Greyscale linked. The backs are between the paper backing and the inside top of the rail. On mine, the two punched down small tabs are stops so the back can't go further when the film pulls across the film plane. They face downward (EDIT: I meant upward, stopping agaist the rails. Not a good idea to wake up and 2:00am and decide to post on RFF 
). The larger punch-out is to move the back plate into position. On mine the larger punch-out would be on top, as would be the smaller one on the other end. The smaller one on the other end seems to be the same, to help position the plate. My thought was that if the spring with the marks had been unnaturally stressed, they might not put the correct amount of pressure on the plate. I have one that I think I am going to need work on the springs as they are a little weak.
I am curious about the back I linked to, after I compared it to mine. They are not the same. I don't know why. I know there was more than one model, but I don't know which one Greyscale has nor which one now on ebay would fit.
As an aside, another thing Greyscale should check is to ensure the film plane moves forward and backward with turning of the focus wheel. There are two springs which move the film plane towards the lens when the focus wheel is turned. Eccentrics move the film plane back. Those springs are often missing. They can be can be made on a brake but you need a template of another spring as they have an odd shape, and to check what size wire to use.

I have one of these wonders and would not part with it...
The pressure plate may be available here and there but perhaps you best run a wanted advert or acquire a complete camera and swap out parts, unless it is in better shape. (Am sure you figured this out already.)
Jurgen somewhere posted he was not a fan, for all the springs and small parts, etc...maybe that has changed.
These gems show up from time to time, but not all that often. I think they are well worth the time and effort and better than the Zeiss 6s.
