Question....Firewall Insulation Fasteners - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Dumb question, but is there a trick/technique/tool to install the firewall insulation retention fasteners? I have tried to put several in and have broken them all. I am not sure if there are other kinds, but what I have are the plastic barbed type.

We have had the original style rubber fasteners reproduced. I never have liked the plastic ones that everyone else offers, because they brake so easy and if you need to pull them out they are done for. We also have most of the other firewall grommets reproduced, and we designed them to be better than original GM. Here is a link: http://www.classicheartbeat.com/rubb...atherstrip.htm
Check them out. You will not be dissapointed. WES

I made a tool once that worked pretty good. If you take a small bolt that fits in the hole in the fastener kind of loose (I think the one I had was about 4" long), put a nut on first, then a washer. Adjust the nut so that when the bolt is inserted into the fastener there is 1/8 to 3/16" between the head of the fastener and the washer. This will stretch the fastener a little before the washer pushes on the head of the fastener. If you can find a bolt that is threaded all the way to the head you can put a washer and nut on it first and thread it all the way up to give a bigger surface to push against. Or you can clamp a small pair of Vise Grips on the bolt at a 90º angle and push against them.

Seems like the rubber ones would be pretty forgiving to install.
