That 8 3/4s a pretty tough mother. I've only broke one and that was in a stick car with a Big Block, and God knows the age of it. And I really can't say " I broke it" because I was just tooling down the road, and all of a sudden ring and pinion locked up. Kind of hilarious, a state trooper drove by his with his wife, telling us to push it and he's got two long-haired kids looking at him shaking his head their heads "NO" Sure Grip, with Sticky Mickys... lol
