I need somebody to re-mount the ground glass on my Mamiya C33. It needs some shims and a couple screws are missing. I can do it, but just can't get around to it. All the lenses have been CLA'd and are sitting there waiting to go. It's one of those projects that has become just one more thing hanging over my head and it's pissing me off because I want to get out and use it. So, who do you recommend?
