What is the best way to swap rear to 5 lug?

[jkade]

I was think on putting the rear out of the blazer in the truck but I hate to start parting it out and that means I will be that much futher behind when I get in the shop. What year axles will work in the 67's rear end? I looked at some from summit but they are $120 a piece. Are the axles out of a 87 down the same? What would you do? Would I be better off to pull mine and send them and have them redrilled? Are the 5 lug and 6 lug drums the same or will the interchange? Thanks In Advance
