Lyle,
The couplers mount to the shells, not the frame, and there are
mounting pads on the insides of the shells for the couplers.
Only the 'B' unit has I-beams under the floor and if I
remember correctly (8 years ago!) I used a Dremel tool to grind
away as much solder as I could and then used heat to release the
beams.
There really isn't a truck mount on the Hallmark frame- only a
hole for the original truck screw. I just elongated the hole
towards the center of the frame so the home-made bolster pin was
properly located for the Proto truck. If you measure the distance
from the mounting hole to the center axle on the Hallmark truck,
that gives you an idea on how far you have to elongate it. Once
you have the hole relocated you can measure where to make the
curved slot for the truck leads and how much to grind away on the
frame ends for the gear towers to properly swivel. As I said
before- this conversion was pretty much fly-by-night and involved
a lot of file & fit, file & fit until I made the idea
work!

John, thanks for the images. Your method is making me reconsider
what I thought I was going to do. A couple of things tho'. I
don't recognize how you mounted the couplers and their mounts. It
appears you maintained the original mounts but how you attached
them to either the shell or the frame is not apparent to me. Are
they still on the short piece of the frame that you removed from
each end? Also, just to confirm, the I-beam appears to be
originally mounted by two solder points each. Did you remove them
by using heat or can they be pried away? I suspect the former. The
original truck mount, did you remove it before opening the floor
or were you able to remove it piece of the floor you cut away?
Again, thanks for the images, they will be of great assistance
