You won't be able to swap out to a factory 5 lug axle, which started in '71, because they are roughly 1/2" longer. GM did this to compensate for the slightly wider track width in the front created by incorperating the disc brake spindles the same year. There are a few suppliers that offer aftermarket replacements in 5 lug. Early Classic sells Dutchman Motorsports alloy axles (around $300), but they are upgraded to a 30 spline end. If you go this route, they also carry new spider gears for the rear end carrier that have the corresponding 30 spline holes. This also increases the load capabilities of the axle. It's not all too complicated changing the axles, just need basic hand tools.
