[Old Chevy Lover]

I had a PowerTrax in a 10 bolt 64' Chevy II that I raced, and it worked flawlessly. Nice thing about these are that they are locked together 'until' you turn a corner. No danger of it unlocking on a straight... only drawback to these units are if its gonna be a daily driver, on wet roads going into a corner on the throttle, it WILL scoot the front tires until you let off enough to unlock it. At least that's how mine was, and my brother had one in a 10 bolt 84 4x4. His was the same way. The offer a newer verison now that is supposed to be quieter (you don't hear the clicking while turning corners). Personally, I liked the clicking. (let me know it was unlocked). Hope this helps
