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

Wes at Classic Heartbeat has the correct ones. I got mine from him.
