Rob,

You're going to need to be the source for those dimensions. I only drilled
for the one on the driver's side since that's the one that always causes me
trouble. I located it by drilling through the support with the engine and
transmission removed. I can remove the cover over it and take a
photograph, but I don't have any reference point for either horizontal or
vertical dimensions -- everything's covered with carpet and cabinets on top
of that -- there's just too much room for error on any measurement I might
make.

With the riser removed as in your photo, it would be very easy to find the
correct location for the holes. Since the subject bolts are 3/8" (9/16"
hex), the holes need to be large enough to pass that socket, with a little
leeway. I'd probably make them 1-1/4" or 1-1/2" and cover them with 1/8"
thick aluminum plates and gaskets. My carpet's permanently attached there,
so it was lucky that I have a carpeted, removable, 1x3 there as a guide for
the "Gas Powered Dining Table" -- that covers the hole nicely without
having to rip the carpet out. Anyone planning far enough ahead could make
the carpet removable.

Let me know if you still want the perhaps worthless photo.
