Universal type. I could mold these in and smooth them out to the body, they'd be much easier to do. But I could do it either way, well leave that for the polls.
I'd kinda like to make glass replicas of the bumpers and customize them to be more flat and hang lower to the ground. Nothing fancy, just more Nascar like. That would definitely be a process though, because I would be venturing into new waters, deep waters. But I'm sure I could make it happen given enough time.
