ford 8.8" and chrysler 9.25" ring and pinion notched cross pin

for anyone who is familiar with the issue with the Ford 8.8" and Chrysler 9.25" rear differentials , with ring and pinions geared 4.56 and numerically higher ( 4.56 and 4.88 ) , there are 2 schools of thought on these , the first being actaully grinding material off the cross pin that holds the gears in the diff carrier , and the 2nd being buying a notched cross pin that is made with a notch in the cross pin , after much discussion with some of our suppliers we have found they all seem to agree that buying a notched cross pin is a better choice , than griding / machining the existing cross pin , some believe that maching the cross pin compromises the integerity of the cross pin , and there is no widely accepted amount that needs to be machined off the pin , plus it would be a giant pain , and probably cost more than the cost of a factory notched pin , to take it and have it professionally machined
