Wheel Vintiques makes steelies. I think you can get at least 10" wide rims. They are in black primer ready for paint, have lugs for hubcaps. But are not cheap.... That is the next thing for my truck, 16" deep white steel with dog dish hubcaps.
Oh my, you have a VICA banner. I was in VICA 80 & 81. Wow haven't seen or heard that in years!! I was a machinist in Machine Trades class. Thanks for the memories.
Welcome from Ohio. I'm old school, I'd recommend big block. I'm old, drive around gently and my 496 is surprisingly better on fuel than my last truck with a 350.
