Hello everyone! New member here seeking some information about paint colors. I’ve Googled what I can and cannot find all the information I need so I’m hoping there are some knowledgeable people here.

I’d like to know what colors Dodge used when painting the engine bay side of the fender wells, underside of floorboards and chassis rails in the 1972-1974 D300 models. I know it’s typical that Dodge painted firewalls, inner fenders and fender wells body color but I’m seeing conflicting information when I search and I cannot find any information on chassis frame rails or floorboards.

Any information would be helpful. Thanks.
