This is the center tunnel from the donor car, turned upside down.

This is what the center weld point looks like. The bracket shown is from the early tunnel. The later tunnels have a more oval hole in the bracket. Our bracket had the whole right side gone.

This is the firewall from the donor to show what it's supposed to look like.

This is what our firewall looked like. We were surprised to find out that all the metal was still there. We just had to bend it back into shape from the inside of the tunnel. Our original plan was to replace a piece of the firewall from the donor along with using the the tube from the donor as well. It turned out to be easier to put the original tube back into the tunnel and fix the firewall.

Front tube bracket #2. The brazing that you see came back to haunt us later.

This is the flap we cut in the front of the tunnel. Tape shows the measurement from the shifter hole

The front bracket as originally repaired. We just welded the bracket where it had originally broken.

We cut a piece from the donor's old tunnel to make a "bracket" for the center weld point. It was easier to weld it to the floor of the tunnel than to try to rebuild the factory bracket.

The center weld after it was finished. You can see how little of the original bracket was left.

The firewall was repaired by bending the metal back into as flat a shape as we could get, then using an appropriate washer that was cut into a "D" to fit and welding it in place.

Mike was not happy with the way the welding came out. I'm sure it will hold just fine. It looks better after I worked on it with the grinder. It's hard to reach a lot of places in that space. Once it is painted it will look just fine by me.

The engine end of our tube was bent and out of round. Mike pounded a spike into it to fix these problems, but the force ended up breaking the middle weld where the bracket attached to the tube and the front weld where the bracket attached to the wall. The pre-existing brazing on the front seemed to be the problem.

The middle was just rewelded. The front was fixed using a trick that Brad Roberts posted. Mike drilled holes through the wall and the bracket, then welded through the holes. This worked quite well. For those who only have a broken front bracket, this might be the only thing you need to do instead of cutting the flaps for access to the inside of the tunnel.

Here's Brad's Repair Thread

My welder at work. I can't say thanks enough for Mike taking a weekend to come up from Phoenix with his welder to do this job. Thanks Mike! (IMG:http://www.914world.com/bbs2/html/emoticons/pray.gif)

It was only 44F and the wind was blowing when we did this job. Fortunately I had the pieces of a recently removed fiberglass tub/shower to use as wind breaks.

As clutch cable tube repair jobs go, I would guess that this is about as involved as they can be since the tube had broken free in all three places. The hole in the fire wall was large enough that I was actually able to pull the tube out through the firewall.

Hopefully this will help others who face this common repair job.
