7 1/4 Rear Differential ~ Experiences

My personal experience with a 7-1/4. Mine was a sure-grip. I beat the living **** outta that rear behind a stock 273, a mild 318 & later a warmed over 360. Damn thing never failed. Not a peep!

My best friend's 7-1/4- not so much luck. '70 Duster, 225 /6 3sp manual. Again we beat the **** outta the car & it worked fine until 1 day when he went to Burger King to get lunch for the guys at work, right in the middle of the lunch rush hour, just as he let the clutch out to pull away from the drive in window..POW!! BANG!! The spider gear pin blew right through the rear cover & locked the whole rear up! Right in front of the drive-in wiondow! At the peak of the lunch time rush! Oh man the line of cars honking & people cursing at him as he tried to push it away! Uh-Uhh! No way was this thing moving! About an hour & 1/2 later the tow truck was able to clear it out of the way. The Burger King manager was pissed! Not to mention when we got back to work with everybody's cold lunch how much **** he took for it!
