When a roll cage bar/chassis tube goes through a firewall, what do you do? Do you cut the hole close and then weld around it, use seam sealer, just live with a small gap? I am trying to decide what to do with bars connecting the cage to the front and rear suspension points. Thanks, John |

My holes are tight. 1/8" bigger than my tube. I used black silicone to seal the gap. Looks good and I don't need an extra cover plate.

You can see in the background the tube going through the firewall. It's welded to the hoop and the rear shock tower through the factory hole. The firewall was cut with a hole saw...   |
