Back in the mid 80’s I ran a Chevy circle track car with a stock 10” rear and we never broke a C-clip but we did break a right side axle once. After that happened we would replace the right side axel halfway through the season. The real problem is twisting an axle since there’s nothing to hold in the housing after it breaks. I would have rather ran a Mopar but we couldn’t afford to build a new race car and always ran used race cars. Also spare Mopar parts at the racetrack were non-existent since everything was Chevrolet.
