Leaf front under 79???

How hard is it to get a leaf spring axle under a 79. Ive seen a few on here and other sites as well. Im wanting a lot of lift and this seems the way to go. I may end up taking it to a shop anyway, but would like to know what all is involved anyways. Thanks Or do you all think that a 9" sus with a 3"body would be enough for 44's if so I can just use a d60 and stay with coils
