firewall plug question
 

Where are you guys buying your firewall plugs? I want to seal this cab up tight, but I've got about 3 or 4 holes where wires or windshield washer lines come out. I haven't found any plugs/grommets in any catalogs.

I really need the lower circled opening plug. The upper circle is a secondary hole near where the washer lines are popping out.

I bought some from the Truck Shop in Orange Kalifornia. They were $4.00 each and crap. They were made from urethane and won't stay in the hole. I tried to adjust the prongs just once and the prong snapped off. Find some good used ones and clean them up.

I found plugs at the local hardware store in their bins of hardware. All sorts of goodies there.

napa car parts sells packages of nice plastic plugs in a verity of sizes they work great
or check your local auto parts store by the vacumme caps ect.. they usally carry them.

That plug in the lower circle is where the clutch linkage comes out and is held on by a screw. I get them at the junkyard off of factory automatic trucks. It's metal with a rubber gasket behind it.

TX Firefighter - I saw one of those a week or two ago at the junkyard. Since most of the older ones are going to be pretty nasty/rusted I'll just make one out of sheetmetal and paint it to match the firewall. Thankf or the help, and sorry for the late reply. I was just cleaning out some of my subscriptions and thought I should respond to this one.
