1/2 ton axel up grade ?

[shakedown96]

if you read my introduction thread (dont mean to be rude but...) you know what I have for parts to up grade for strength. I plan on doing some offroad touring nothing past a #4 trail.

as I under stand the 14bolt ff is the way to go there is one in both doner trucks witch is the best 78 3/4 or 94 1ton? they are both open with 3.73.

the next queston is i have a 71 3/4 ton 2 wheel with a dana 60 w/factory locker with 4.11 gears I will most likly only ever go up to 33'smay be 35's would you
a) put this axle in the rear?

b) save the locker for a front dana 60? or will it not work in a front?

c) this is over kill you wont need it with the lighter wheeling you will do.

just tryin to plan out the best combo for what I got. I would love to stay with 15" wheels for the street even with the 8 lug
