Decided to use aircraft safety wire instead of welding…pictures detail the repair. The repair itself took about 30 min.

I love the pics, wire will work for a while as a temp fix. Good idea.

My bet is the the braided stainless steel safety wire will last longer than the original weld did, I hope anyway.

Once you get the pedal cluster out there is enough room to get a small camera inside the tunnel

Perhaps you can tell me how that will stop the longitudinal movement? You know, the movement that causes the rear weld to break? Excuse my Krusty welcome, but that's just me, the guy with an attitude. My experience (34 years of teeners) tells me your efforts, clever as they may be, aren't gonna prevent further damage. Nice pix, though. The Cap'n

Lol or you can do what I did which is what the guy before me did... Take a hose clamp to it... same idea different thing used. Hopefully it will hold up. How the heck would you spray all of the tunnel with a coat? Mine is hecka rusty too!

I worried about that as well. The middle weld and the firewall weld on my clutch tube seem to be good as there was no longitudinal movement with the tube. When I installed the safety wire I secured one strand in front of the forward bracket and one strand aft of the bracket thinking that this would also prevent longitudinal movement. About 1000 miles so far and the clutch performs wonderfully, but you may be right, I'll keep you posted

Metal ready or Ospho... watery like stuff. I guess you'd just spray as much as you can or leave a nice puddle of it up front and jack the car up (IMG:style_emoticons/default/biggrin.gif)

Good temporary fix, but I agree with the Capt'n - you will have failure of the other welds unless this one is fixed properly. What happens is that once one of the welds is broken, the longitudinal stress has to be supported by the remaining welds - so their stress level goes up, and those welds will fail. Might be 5 months, might be 5 years, but it will happen.

Great photos though!! (IMG:style_emoticons/default/clap56.gif)

I had mine done years ago by my mechanic in CA (Bob Grigsby). He took the shotgun approach - he welded it AND he used clamps along the length. It's never going to move again.

Now that the tube is pulled up tight and the bracket is located, it's a real easy job to drill 2 holes and plug weld with a MIG.

Probably won't take 1/2 hour from start to finish. You did the hard parts (location and getting the tube pulled tight against the tunnel).

It's been said clearly. What I was thinking. You did a fantastic job of securing the tube the the tunnel. But the real problem is... The actual-use tension is not sideways, it's backwards. Your fix just might hold it... But it's still a *might*. It needs some strength to handle the forward/back motion.

What John said, Although 30 mins is a little long.. I'd say 5 mins...

Do it once, Do it right, DONT blow through.

I used clamps till I bought my welder, Worked just fine.

I was giving him time to park the car, pull the carpet back, find a drill, find an extension cord, drill holes, find a vacuum, vacuum the metal shavings, find a grinder, scrape some tar off, grind a little paint, vacuum the dirt, get the welder, unroll the leads, plug in the welder, find the hood, find the gloves, turn on the gas, weld two spot welds, touch up the paint, and put everything away.

I'd say 1/2 hour.
