From the looks of the 4 gear truetrac, you must be using 31 splines at the diff end of the axle. Even then, it looks like the axle shafts are necked down below the minor diameter of the splines.
Majority opinion says that with the power your motor makes, that you would need 35 spline axles. Does the lack of bending load from the "floater" setup, make that much difference? I guess if you never plan to run a drag slick, the tire is the breaking point. Just wondering why 31 spline, what is the reasoning behind that choice? Does the corvette bearing limit it? Is 300M worth that much? I just went through this with my car (simlar power) and ended up with 35 spline axles and truetrac.
