Emmerrrrr

Im limited locker options for the rubicon because of the 32 spline. Im anti arb. I only buy eaton. Rumor while back was they were making a detroit release would be jan or feb. I called today now theres no site on it theres possibly a elocker coming but aways down the rd. So my question is now the rear shafts 32 spline at the carrier but drops down in diameter towards ends of shaft. So could I just purchase a 30 spline detroit locker and good aftermarket shafts at 30 spline should be stronger cause its same diameter the whole way through the shaft?
