Also, on an intersting side note, I have heard from several sources that the firewalls on these trucks were painted the same metallic beige as the interiors. However, I can find no evidence of this on either of my cabs. Both were originally brigade blue, and although both trucks were repainted, the firewalls were not, and both appear to be painted the primary body color. I have included two pictures of the firewalls to illustrate this, you can see the top layer of blue paint with red primer directly underneath. Maybe it varied based on assembly plant?
