 Hey guys,

I think I had a tech tip about this published in either the Richmond or
Capital Triumph Register newsletter.
What I ended up doing was getting some realatively long - (like an inch to
and inch and a half) set screws that were the same diameter / pitch as the
bolts that hold the cover down.

I could screw those down into the holes from inside the car using an allen
wrench.
Then what I've got is a bunch of studs sticking up out of the flange on the
floor.

Pushing the tunnel down onto these studs is MUCH more easy than trying to
line up the hole in the cover with the hole in the floor.

Then you can put whatever washers and nut you want on to the top of the
exposed set screw and tighten things down.

You'll end up using the allen wrench to adjust how much of the set screw you
want sticking up above the nutt / washer . . . so it is a little fiddly
having an allen wrench and some other type of wrench working at the same
time.
(Much like adjusting valves)

For that reason -  for some of the fasteners that were difficult to reach -
if the tunnel seemed to stay in place well enough - I went ahead and pulled
the stud (setscrew) back out and replaced it with a regular bolt.


I'm trying to remember if there were any other things I learned when doing
this .. . .
I believe depending on your car - there may be a couple places where the 1
1/2" long studs can't be screwed all the way down.
They stick so far out the bottom that they might hit . . .something  . .and
exhaust pipe or clamp maybe?
Not sure.

I am pretty sure I used stainless steel setscrews.

maybe these:
