Wanting to swap to 4.10 gears... cheapest route?

[Campbel45]

So I know I will be wanting to swap my front axle's 3.08 gears to 4.10 here soon.. but I'm not sure what the best route is. Do I swap in a dana44 HD axle or change my carrier and gears on the axle I have? What would you do?

- I have a 1971 shortbed K10, sm465/np205, 4" lift.
- I DO NOT want to increase the overall height of the truck. I'm just barely able to get it in the garage.
- I also want to keep the 15" stock steel, 6 bolt, rims I'm currently using. (I was planning on swapping the knuckles between dana 44 and dana 44HD)

Thanks for the help guys
