You need to measure your rear end to determine which axles you need. Measure backing plate to backing plate. The narrow rear end is 55 inches. If that is what you have, you will have to get conversion axles like Moser (I had to do this). If you have the wide rear end that measures 57.5 inches (I think) you can use the 5 lug axles off a 71 or 72 that you can pull from a junk yard or get off the parts board here.

From what I've read on here, the 70 models had a mix of wide and narrow rears. It is also possible that it has been changed/replaced over the years. Its best to measure first so you know what you are dealing with.
