Hi! I basically have a trail as my driveway on which I drive my 1991 HB 2wd pick-up through everyday. I can honestly say that at least two times a week I'd get stuck because only one wheel turns so I'd end up framing out. Is there a way I can make the rear of my truck into a positrack or perhaps swap axles with a 4x4 model to get both tires turning for optimal traction without the excessive wheel hop and price tag? Thanks for your help.
