Build some! Its really not hard, and performance is ridiculous! Camburgs are pricey but I needed new ball joints so I bought them. They really reduced bump steer with the heavy tires and these 1" uniball joints will never wear out which is what I wanted. With the amount I'm offroad I'd go through stock ball joints every 15-20k miles.
So if I do the towing mirrors, should I paints the caps like my current mirrors? Or PTM the whole mirror with chrome caps? I like both looks, can't decide. I think either would look good on mine, leaning a bit more toward PTM caps with a custom LED array. We'll see.
