Well.....I've kind of wondering the same thing about driveshaft loops/ safety items. After spending some quality time under my truck today changing oil, lubing what few fittings there are these days, I noticed, with much dismay.....you can't put a driveshaft safety loop on a reg cab, short bed truck. The driveshaft is aft of the main frame rails, and right beside the gas tank! I don't know about the other body styles, but there's just no place to attach any kind of bracketry. Any one got any other ideas?
