Always a pleasure to share/help; the least I could do to give back to the community that helped me find and restore/maintain my ideal no-frills minimalist, simple but reliable utility vehicle.
I think total would have taken a whole weekend. However, it spread out over several days because I also took care of details that needed attention (i.e., surface rust where clutch master cylinder dripped brake fluid) while I had the panels off. The job did not keep me from daily-driving the truck. Some days, I drove the truck with only the driver seat installed
Before hand, you also need to spend time researching and shopping for materials.
IIRC, I used:
5 rolls of Peel and Seal. Good for total coverage, including firewall and tailgate (which I haven't done, yet)
One roll of thermal insulation from Pep Boys. Used it on firewall, tranny hump, and left side of floor (above exhaust pipe).
A $20 roll of diamond-plate anti-fatigue mat, although I think heavy-density exercise mat would do a better sound insulating job. Anyway, just find out which would cover the floor & firewall for best price.
Some of the wind noise is from wind on windows and windshield so nothing we can do about that.
However, a couple of things I'm considering:
1) Some noise is from leaks around the door weatherstripping that had probably lost some of its loft. Replacing that with new one should help, although not sure if still available. An option that I'm considering is an eight of an inch thickness of rubber/foam on door frame where the weather stripping contacts it. That would make the fit/seal tighter. You must have noticed that some newer cars have weatherstripping on both the door and the door frame itself.
Because some wind noise also comes from the roof..
2) Remove headliner and existing foam insulation from roof, replace insulation with something denser, like the exercise mat. Re-install headliner. AND
3) Since there's plenty of space between head and headliner, Id like to install a storage compartment there. It would be a semi-rigid (foam backed)
modified version of the hanging pocket storage
like this. Sleeping pads would be stored there, and during road-trips soft articles like clothes as well to conserve space. Even when empty that additional material between ceiling and head would help insulate. Would do same under the Fiberglas cap.
Your thoughts?
