I am not exactly sure what you're asking, but here is a brief summary of my

I was performing an engine swap on my 66 roadster, when a late model OD
tranny became available (OD in 4th only). So I acquired it, and the new
backplate, flywheel, etc. I bought the tunnel cover from BA, and it worked
very well, although I found that the plastic used was very difficult to cut
with hand tools (you have to cut out the hole for the shifter -- I suppose
this gives you the choice of using the round boot or the oval one).

I have never understood what is meant by "bashing" in this context. You have
to CUT the opening on top of the tunnel, extending it about 2 inches to the
rear, to accommodate the new shifter location (this is the purpose for the
new tunnel cover). But I didn't have to "bash" anything. I think people are
referring to banging out the tunnel side to clear the starter or the
bellhousing somewhere, but I didn't have any interference problems at all.
Perhaps it makes a difference what motor mounts or tranny mount you use. I
don't know.

About the OD switch, if you mean where do you put it, my B already had a
hole in the dash to the left of the instrument cluster. Any generic toggle
switch will work -- I started with a cheesy one from Kragen's, but replaced
it with a used wiper switch for consistent styling. This hole, BTW, seemed
like it was a factory cutout, that perhaps had been filled with a blanking
plug -- to the further left of it was an obviously PO-cut hole (who knows
what for) which I filled with a spare ignition warning light unit, as an "OD
warning light" to help me remember to switch the OD off. I wired the lamp to
be on whenever the dash switch was on (regardless of whether the OD was
engaged, as controlled by the lockout switch); the idea being to prevent the
scenario where one would forget that the OD switch was on, since the tranny
would automatically drop out of OD when one downshifted, and then upon
shifting up one would suddenly find acceleration terminated by the
