Ok, Joe found a photo that shows the concept but this was
my first Lou Ross PSRU. I wanted to retain the same
mounting position when I decided to adopted Tracy's RD1C but naturally he
did not conveniently make his mounting plate to meet my needs {:>). So
I reshaped the mounting tab into a triangle with a bolt hole on one end
and then cut a slot in the mounting Bolts (not all the way through
only far enough to capture Tracy's mounting bolt.
In any case, this should give you the idea - note my
engine is rotated 90 deg CW.
