Bill,

Yes, I'm afraid this discussion began under another topic. What we're
trying to deterrmine is useable dimensions for drilling access holes
through the lower cockput step riser behind each of the 3 bolts which
attach the rear transmission mount (the "sheet metal" affair) to the bell
housing. For some of us, installing those bolts is a real PITA (sometimes
takes me as long as the rest of the transmission installation). For ANYONE
who modifies the step to each side of the chain housing, so that there's no
access from the sides, it will be might-nigh impossible.

With the plywood removed from the step, you can probably measure where
those riser holes should be located, and hopefully record those dimensions
in reference to some fixed, readily determined location, regardless of the
state of carpet and cabinets in the area. I suspect it will be necessary
to measure the lateral center of the engine hatch and extend a line down
from there to the lower step riser. One could then measure laterally from
that line and vertically from the top surface of the lower step and be
pretty darned close -- certainly close enough for a 1-1/2" hole to allow a
9/16" socket and extension to reach each bolt heads.
