Question Re: Changing rearend gears to posi

Just found out my 64 Posi gears are 17 spline. My 72 rearend has 30 spline axles. I want to use the Posi gears on the 72 rearend, but the 30 spline axles won't fit. What are my options here?

Should I get a machine shop to redrill my 17 spline axles to 5 lugs, or are there 5 lug 17 axles from other 12 bolt rearends that interchange?

Should I consider other options? Thanks guys.
