Kevin, what is the reason to install the Kick Panels that early in the process? I had assumed they go in after the carpet to cover the edge of the carpet?
The kick panels are a pain to install, you need to install them first so you have room to work (remember to replace the Dum-Dum putty for a good seal). Pass side is "almost" impossible with the heater installed. By doing them early, you save yourself a bunch of skinned knuckles and cursing.
The carpet is "tucked" under the kick panels (and firewall pad) later.
Certain other things are more flexible, like the ebrake, once the firewall pad and drivers kick panel is done, the ebrake can go in, or you can wait until carpet is done, since that is easy to install.
There are some little things that I did not mention, but get installed during the main electric harness step. high beam switch, flasher that gets mounted to the dash support, ebrake light, plug from main to rear harness, ground leads, basically anything that gets plugged in or screwed to the body frame.
Some tips, NOW is the time to take a close look at the rubber seals for the kick panel vents, defroster duct, heater box and astro vents! Replace them with weather resistant rubber before you install them. Finding out later that they are letting in all this air flow is very time consuming to replace later. I used sheet rubber/foam goods from Mcmaster and cut my own, the repro kits are a joke.
Also inspect your astro vents for any cracked or broken lines, now is the time to fix or replace these too! And replace the chrome astro vent louvers too
