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 |

Just an observation:
1 - For the fronts, the heater hose holes are perfectly lined up to put a support from my front suspension shock tower plate to the base of my rollbar. I am considering putting a support in there, but there is some confusion about whether I am allowed to do this or not in vintage racing (I'll wait a season or two). 2 - 914s have THREE firewalls: One between engine & driver, one between gas tank & driver, and one between front trunk & gas tank. Since I removed my gas tank and replaced it with a fuel cell in the front trunk, WHICH wall is my firewall now? Stu |
