741 open case v 7 1/4 LSD

8-3/4… For So Many Reasons! Look at the 2 inch axle tube size into the center section for starters, and then go from there. Just the spindly size of the housing with tubes by itself would scare me far away from the 7-1/4, much less my personal experience in breaking them. And with nowhere near the torque output of a good 440, at that!
