so I'm wondering if anyone has used the firewall along with the floor of a donor vehicle? I was originally going to use a yellow caterpillar service truck and leave it like it is patina and all. Now that I'm using an aviator chassis and everything I can use from it. I'm thinking it needs to be in a truck that has a nice paint job. Then I can also match the tan interior. I happen to have another truck that is really straight, but the floor and firewall are totally shot. I realize matching the 2 up is probably going to be a beating, but what the heck? Unless it's impossible? Measurements match up pretty close.
