If I did anything, it would a slight drop. A shop logo would hurt the clean loo of your truck IMHO. Whatever you do KEEP THE HUBCAPS if you are not changing wheels!!!
Here's a clean, slighty lowered, stock-looking '67 for reference.
If you want a little more hotrod, chopped up look, you could alway get some 8" steelies for the rear like I did my beater truck when you do the drop.
A set of Torq Thrusts and redlines would be absolutely beautiful with your interior (and would match the camaro!).
Here's some more inspiration!
