Update for October 18th, 2009
With the weather finally cooperating, much was accomplished this past weekend. For those who have been watching, the firewall area around the drivers area has been in heavy work, both preparing for new insulation/sound deadening material(s), as well as restoration of the brake/clutch pedal assembly, and swapover to power brakes. This has been a huge project, I probably spent 10 hours in the car this weekend alone.
On to the show - Pic 1 shows the installation of "FatMat" sound deadening material to the firewall area. This material dampens vibrations, and is a good heat/cold block as well. It has a very sticky backing, and once on, is virtually impossible to peel off. This material was carefully cut to the firewall, and up around the cowl underside.
Pic 2 - on top of the Fatmat, I am adding a vinyl/foam barrier for sound reduction. This material is made by "Second Skin", and will replace the old, scrungy jute/rubber firewall pad. Now, in order to "fit" it properly. I used the original firewall jute pad as a guide for cutting holes in the proper places; note them side by side.
Pic 3 - Here, the small but important "gas pedal plate" has been added to the material, just as it was in the factory pad (placed in the pad, and gently "hammered" so that it grips the pad). Now, with some careful cutting, the pad will be installed to the firewall using spray contact cement.
