Firewall Insulation ?
Did any of you guys shave off the holes on the firewall for the firewall insulation plugs. I just dont like the look of them sticking out . Oh I live in ontairo so what options do I have to insulate the fire wall? can you buy stuff that sticks on? thanks . Just trying to smooth things out the old hole for the clutch linkage is smoothed out and it looks alot nicer already.

I'm doing the same thing 72MARIO. Nothing on the firewall but steering column and brakes. The No-Limit catalog lists an inside insulator/pad, for our trucks. I'm going to check them out. It'll be a little while for me, if you find out anything, let me know. I know some people has just glued the foil backed deadener on the inside.

I covered the firewall/cowel with the stick on sound deadner similar to dynamat. (There are a number of different brands, some a less expensive.) On top of that I used the original type of padding with the cardboard backing. The areas where the original insulation didn't cover I glued on insulation with foil backing. In fact I lined the whole inside the cab with sound deadner and insulation. In the doors I just used the stick on sound deadner (insulation would retain water) and sprayed sound deadner on top of that. Underneath the door panels I used even more. I haven't had the truck on the road yet to see if all this insulation (well over 100 square feet) will make a difference. The doors close with a satisfying "clunk" rather than the tinny sound it used to make. (Tap on the side of the box and you know what I mean about a tinny sound.)

If it were me...and you wanted to clean the
firewall up....and you planned on welding up the extra holes....get some 1/4" bolts with the flat heads (very flat, dont know what you call them) and weld them in...approx the same lenth as the rubber retainers. You wouldnt be able to see them from the firewall side, but you could then put a flat fender washer on from the inside using a nylock type of nut to retain the insulation pad and it wont come loose or fall down ever, If done right, it would also look very factory! I just dont see how any kind of glue would hold up over time and trying to stick the factory style 'jute' insulation would be a nightmare. ------------------ 71 Chevy C-10 SWB Fleetside WAS:307w/3-on-the-tree NOW:350TBI/700R4/3.73 See it at www.prismnet.com/~grzanich
