Best way to add 2"-3" lift on my '66 GMC 2wd

[Backpayne]

I am wanting to lift my '66 just a couple of inches and was wondering what is the best way to do this? Would the spring spacers with ball joint spacers on the front and lift shackles/blocks in back be the way to go? A frame swap with a 4x4 is what I'd really like to do, but I am struggling with finding something at this time.

Do they make a body lift kit for the '63-'66 Chevy GMC pickups?

Thanks!
