4x2 to 4x4

[spritemaster]

I have a 1977 jeep mail truck that I want to turn into a trail jeep. It's 2wd and I need a 4x4. How do I convert it?

Front driveshaft too. Jeep mail truck, sweet. Are you going to keep the original paint? It's a must.

I'm definetly going to keep it looking like a mail truck but it's gonna have everything it needs to hit the trails to.
