I went...

    Test Mule-Still Kick’n

    The G80 reverts back to a limited slip or better known as posi traction after the locker disengages after 25 mph. The lunchbox and the aussie ratchets are aftermarket with poor road manners. The G80 was and may still be a GM option in a huge number of their trucks and vans

    Hello As you can tell from the photo, my build is a head scratcher to most so allow me to explain myself. First and foremost I can’t leave anything alone. Most everything I’ve ever driven has seen mods, some good some bad. Like my attempts at land speed racing on antique Harley Davidsons, I...

    Thanks for the add-here’s my rig. ‘99 GMC Safari AWD. For the last 11yrs I’ve been active with the Boy Scouts of America, the last 4 as Scout Master. I picked this vehicle for its simplicity, its ease of maintenance and it seats eight. The awd feature made pulling the troop trailer in all...
