Not sure why by one of my POs has used a U-bolt to hold down one of the tubes in the tunnel. At this point I am not sure what goes in the tube (poor documentation on my part), but anyway I am wondering if there is a better way to repair this.
 Someone cut a couple extra holes in the top of the tunnel and it looks like the brace for this tube was welded to the location where the hole was cut. Or maybe the brace broke.  and finally a shot from under the car.  This is the larger of the the 2 tubes running to the pedal cluster. The smaller one is tucked up high on the top side near the driver. Q1: Clutch or Accel? Q2: Should I just leave the u-bolt? Better idea? Q3: surface rust throughout the tunnel. Impossible to get to. I was thinking of using the Eastwood interior frame spray as a rust killer. Better ideas? Thanks, Clark |

The front needs to be axially secure, and a u-bolt isn't going to provide that without crushing the tube. Get the clamp out, locate the original position for the front bracket, and repair it properly. Weld it rather than braze, because brass is prone to failure from vibration.

The Cap'n Cap'n, the u-bolt was really tight. And I now understand that the "thru firewall" point needs to be very secure. Which is on me to secure when I replace the firewall. There is one more strap close to the pedals but it not tight, only holding the tube in the high position. This thing broke loose from a couple factory welds, I don't see me or anyone really doing a better job than the factory on this thing. Especially with all that surface rust to remove and get a good hold. I don't see this thing moving. What do you mean by axial? Up-down & side to side or spinning on the tube's axis? |
