Rich,
I think the only one who would have that
measurement is whoever has the plans for the PSRU. 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.

question
In Tracy's
prsu, the forward oil seal is in a circular aluminum piece which is attached to
the prsu by several Allen bolts which are arranged in groups of two. What I was
looking for is the diameter of the bolt circle and the spacing of those
bolts
My bracket will be a flat steel plate affixed to the front of this
plate using 3 of the bolts. The brush/rpm sensor will be connected through an
ear on this plate
Rich,
If I understand what you are asking, I
think Tracy’s PSRU has a SAE
2 flange. The dimensions are in this gif.

I have already designed the mounting plate
All I really need is the spacing of the bolts so I can make the fixture
before I disassemble the prsu
Two examples for MT props.
