I recently picked up an old Polaroid 800 while on a trip to the US, and decided to convert it to shoot 4x5. Since I have some mahogany I am planning to use for an 8x10 I decided to use that. I had to build up the film plane some to get it to cover 4x5 completely, which meant I had to shift the infinity stop farther than the adjustment slots allowed. I drilled two new holes for the stop, but have not been able to find a tap small enough tap them yet. When I do get the stop in place, it looks like I will have to file down the front ears a bit so the carriage can pass over the stop when closing the camera. This shouldn't be a problem, as the camera front is sprung to hold tight to the back. Actually, so far I have not needed the stop, as I merely put int the ground glass, then determined infinity and made a pencil mark on the front and can pull the carriage out to the mark, the use the rangefinder focus knob as normal. Here are some pictures of the mod:
