Does this help? I know you want it with the shifter removed. It will only take a few minutes for me to pull it off if you want more photos of just the hole. Let me know.

AAAAAAAHAA! Thanks Everyone....all the pics helped. Vibguy....you do not need to remove the mechanism!
None of the parts shown in everyone's pics were present when I bought the project-car....the previous owner had a aftermarket hurst shifter laying there connected to the trans so he could move the car when necessary.
now I know what I need to do and where the shifter bolt holes should be located.
I'll peel back the insulation I install 7 years ago and mark the tunnel for shifter bolt holes and make a fiberglass pocket/tunnel patch (that I can add insulation to) for the shifter mechanism to "sit in".

The good thing is....the car was not even close to original when I bought it...so whatever I need to do to make the original style GM shifter fit properly will not de-value the car

Tell me about it. I was ready to reinstall the pressure-washed carpet when I said to myself......
"Do I really want to get fiberglass and resin on the clean carpet ????"
(My first answer was the WRONG one).

I can't believe Someone out there doesn't have a tunnel section to Donate.

Barrist.....it's O.K. ,,,,,I'm going in a different direction with the repair to the tunnel,

The pics everyone posted have all the info I need to fabricate a pocket and to bolt the shift mechanism in the correct spot. I won't use the rubber gaskets and trim ring since the lower part of the mechanism will sit in the insulated pocket which will be MUCH smaller than the hole GM made at the factory.

caskiguy....thanks for the pics.....after reading how much heat can radiate thru the rubber gaskets (I have reinsulated every other area in the interior) I'll go with the plan above.....
(think restomod/mostly mod )

FINALLY....SINCE MARCH 2021.......I dragged myself into the garage to see what it looked like what needed to be done to remove the aftermarket Hurst Ratchet shifter.
NOT a pretty sight but less work than I thought.
I had 1/4 roll of Reflextics left over after insulation the garage rollup door so I used it to put a 2nd layer of insulation on the tunnel.............






It's time to remove the Hurst shifter ****/vent ***** and lift the shifter console to see what kind of tunnel damage is hidden.........



Now, that's a nice hole if yor're a fat racoon.........



The aftermarket shifter is disconnected fromthe cable/unbolted/set aside on the right side of the tunnel for tonight........



Hopefully tomorrow I can clean/sand the tunnel fiberglass/attach a thin sheet of aluminum backer to the underside of the hole/begin laying fiberglass mat over the backer to get a smooth tunnel repair.
Then I can mark bolt-holes in the correct location for the OEM GM shifter and make a waterproof pocket for the bottom of the shifter mechanism to rest in.(WHEW!)

Tony you can use cardboard as a backer as well if the tin foil wont stay in the shape you want. Maybe get a cheap beach ball to semi inflate and put on top of the tranny to hold the cardboard flat against the tunnel. Then you can just pop the ball and slide everything over the tranny onto the floor of the garage

Thanks R.R. I have a sheet if .040 thick aluminum. I'll bend/contour it by hand and use your inflatable ball to hold it tightly against the tunnel from the underside.

My new employer has a 2 sided tape the airforce uses to hold sensors on their jets....the specs on that are insane. You clean the fuselage, paint on an adhesion promoter then apply the part with the tape on it. It can with stand insane heat levels in both extremes and super sonic speeds. They used to use epoxy but the application turn around time was days to weeks where this is hours......science is literally magic, they just changed the name to "science"

The Amnesia doesn't let me remember alot of things, but I do remember wrapping tape around the blades.
The 1st time I wrapped it the wrong way...by the time we got back to base camp the wind had pulled half of it off the blade

Sounds like a good name for it!

Yep, R.R. The late '60s/early '70s were ancient...Nam was the "Test Grounds" for U.S.helicopter anti-tank WIRE-guided missiles. A "spool" of hair-tin wire from the helicopter controls to the missile guided it to the enemy tanks.
Of course, the enemy was also testing their heat-seeking missiles at our helicopters.

But....enough of the good ole days. I'm still trying to work up the energy to make an aluminum pattern to cover the tunnel "gash".

My late friend, Chuck, who spent some time there, mostly with Air America, had a story (the man was a master) re bullet holes. Involves both the USO and some high-rolling General type coming in for a visit. The USO sent, for entertainment purposes, suction-cup equipped arrows and bows.... The Viet Cong provided the next needed itme, bullet holes (I forget if in a chopper or fixed wing). When the General arrived there was an aircraft festooned with arrows.... With the cups removed they fit nicely into the holes. My understanding was that the General was not amused - not that that bothered Chuck!

"400 mph tape" "speed tape"
I can't attest to the origin of either expression, but back in the glory days, when Ford (It's OK, down boys) was palying at LeMans with the GT-40, duct tape got the moniker 200 mileanhour tape as it held the bits of a crashed GT-40 together on the Mulsanne Straight at better than 200 mph.
