RPM 1,190 Report post Posted June 9, 2014 Boy, say that three times real fast :) Anywho, I bought the grommet set for my non a/c heater, and looking at the holes in the firewall something ain't right. No way the grommets will fit. The holes are not a clean punched hole, but have edges which protrude into the engine bay. Did I get a one off car, or are all the holes like this? What did you guys do, grommets, no grommets, use something else? Thanks. Bob Quote Share this post Link to post Share on other sites
Rsanter 152 Report post Posted June 9, 2014 Mine are the same way. I bought those grommets and can't use then either. Look around on the web it looks like some of the cars ( more the 70s ) have the cleaner holes that use the grommets and the 69s have the ones like we have ( not sure about where the change over is) but the cars like ours just used a black puddy sealer that was put on around the hose on the firewall. If it was my car and it was a total hot rod and I didn't care about originality I would either punch the holes clean and use the grommet or better yet I would install a pair of AN bulkhead fittings in the firewall and go that route Bob Quote Share this post Link to post Share on other sites

RPM 1,190 Report post Posted June 9, 2014 Thanks Bob. I never thought of the AN fitting route, that would be slick. I'll probably just seal them up best I can. Bob Quote Share this post Link to post Share on other sites
Brian Conway 264 Report post Posted June 9, 2014 This is what the firewall and heater hoses looks like on my 9/19/68 car. Looks like there are grommets in there with the slop over the top ? I think I would give those expensive pieces of rubber a shot. After all there purpose is to protect the hose. Just a thought. Brian Quote Share this post Link to post Share on other sites
Guillaume69 150 Report post Posted June 9, 2014 Bob, my non A/C heater hoses look exactly as you describe: punched into the engine bay. And I believe they are supposed to look like this because then, you can use them safely without grommets. They have been like this for at least 20 years (i.e. since I got the car), and never had a single scratch on them. Quote Share this post Link to post Share on other sites
Brian Conway 264 Report post Posted June 10, 2014 Got to looking at the pictures here and noticed the shape of the holes in the G69 pictures. Re read Rsanter's OE comments. Looked at my pictures and saw a metal lip/edge in the lower hose Went and got a flashlight and dental pick and took a look. Sure enough all metal no grommet just goop.

RPM 1,190 Report post Posted June 10, 2014 Thanks guys! Guillaume, I think you may be right on the reason for the flared hole. At least it sounds feasonable to my small brain. Bob Quote Share this post Link to post Share on other sites
