Holes in the Firewall...
Hey everyone, I was working on my 68 this weekend and I found a ginormous hole behind the brake booster. It looks as though a grommet belongs there. I checked Brothers and LMC and could not find anything for that specific hole. I was hoping that someone here could let me know where to get whatever seals that up!
here are some pictures Top of booster looking down ![]() Side of booster ![]() Looking up from under the dash ![]() There is also this hole that is covered with duck tape. Anyone know what this is or what goes here? ![]() |

Re: Holes in the Firewall...
GMCPaul or others sell it. It's the pushrod firewall seal. I have it on my 68. (Posted previously): http://67-72chevytrucks.com/vboard/s...d.php?t=379915
Added info: GMC Pauls's site is a little confusing so look here and scroll down to it- pn 8699126. Also you may want to get the boot/seal for the back of the power booster itself just below. pn 2522016. ![]()

Re: Holes in the Firewall...
I had no idea what it even was! Thanks so much guys!!!
What about the hole in the bottom of the firewall near the heater vent/box? Its slightly right behind the gas pedal. Its the hole with the duck tape over it. |

Re: Holes in the Firewall...
alright, I just went to 3 different sites, and it seems as though there are 3 different parts. One of them has a big ol hole in the middle and that seems to be the PN's you guys listed above. Then there is another one with 5 holes. Then there is another one that doesn't have the "lip" like the PN 30-1914 and 2522016.
I checked Southern KY Classics, and it looks like they only have the one with 5 holes ![]() |

Re: Holes in the Firewall...
Wes at Classic Heartbeat has the correct ones. I got mine from him.
