The AHC gas & oil cap is another perfect piece for detail work. An oil cap (with your own design) tucked under the seat is an awesome detail in anyone's book, as is a one-off shift handle or one of my tiny gas caps with some metal tattoo'ing sitting on top of that narrowed tank. When it's covered in road grime it's even better. Initials, numbers, your own design - whatever is in your head. You can also hit Steve up with your own brass or aluminum cap or shift handle and he'll work with that.
