For those with a manual aftermarket system, where did you put your fill ports? Suggestions? I'm not interested in drilling anything that's metal on the truck.
Back in the day, we used air shocks to give our hot rods a decent rake... :) Always put the lines thru the rear license plate holes. Well, except if you had your gas tank fill behind the fold down license plate! Then you just used a tab under the rear bumper, which they all seemed to have as well back then..
