I did this on my K10 a few months ago. I did a build thread on 67-72chevytrucks.com. I did move the axle forward an inch, but you would just need to set yours up off of your dimensions.
The more flexible the front leaf springs are, the more you'll want to push the axle forward to compensate. Otherwise, you will just end up munching the rear fender openings and footwell areas.
