Alloy axle questions

Im Kinda stuck in a corner here. I orderd axle shafts, Superior evolution series for my new cut down hpd44 build im finishing up. Well I got the inners but the chevy outers I need are not in pruduction and im looking at at least 1.5 months and it's not a 100% if they will even have them by then. I could put it together with some spicer 760 u joints and the stock outers for now and run it but is it worth the risk if I blow the ears off the outer and it messes up the ears on my new inners? Or should i mix them up and get warn outers. Im not a Big fan of yukon or alloy usa because they arent thought hardened and there not USA castings there overseas. If i grind my stock outers to take full c clips and run non greas 760's whats more likely to go the ears or the shaft itself in the hub??

Unless you are going to be running some crazy rocks you will be fine running it as it is.
