You will probably have to measure your PSRU in order to get the measurements. The other possibility is that whoever built that plane in one of Bobby's pictures. I don't know whose plane it is, but I suspect it is either Bobby's or Mark Steitle's. They probably just made the plate to fit and don't have the measurements.
