Andy,
I have had good luck in finding "real" backs, that 8x10 cost me
like $7 US, it is metal and has two thumbscrews that allow me to flip it to
vertical or horizontal composition. At the front I installed a filter ring
that allows me to use filter on it. Focal length is 90mm, no real
vignetting.
Here is the back alone:

Here is the back sans GG:

See the square in the middle, it is a flat magnet. I mount a small washer
that I use as my "composing" lens and then I mount the pinhole
(non-magnetic) and keep it in place by putting a big (magnetic) washer on
top. Since I needed to have easy access I removed the GG and mounted it to
a cardboard frame, I also mounted a plastic fresnel reading lens on the GG,
that helps me have a brighter image:

Here are couple of pictures showing the front of the camera and the filter
ring, you can also see the "composing" aperture (AKA washer):

I also have a very nice 5x7 metal back I bought for $10! at a photo fair
(some vendors have no idea what they are selling!! I am not complaining
though!). I have yet to turn it into a pinhole camera.
