Or have a machinist redrill your current axleshafts (if they are usable) or order some 28 spline axles from summit in the correct length for your 6 lug rear.

The later model years 70-72 are the wider axles. The 67-69 axles are 30.75" while the later ones are 31.5". I've ordered a 5 lug conversion from CPP that is currently on backorder. It comes with the 5 lug drums and a new gasket as well for the differential cover.
