Default Drivetrain Recomendation in a 1988 Bronco II

I'm going to be building up a Bronco II, and was wondering what is the best drivetrain combo is(Engine, Axles, Trans). I understand that its going to vary with what kind of terrain and purpose the vehicle is going to be for. With that being said, I'm aiming for the best over all terrained vehicle while still keeping in a refined budget. Lets here your suggestions on the
Engine-
Transmission(manual)-
Axles (front) (rear)-

I'd like to clear at least 35's and retain the Leaf spring rear axle and coils up front.

302/c4/d20

D44 front
9" rear

basically everything from an Early bronco, to keep the axles narrow

An 8.8 out of an exlporer would also be a good choice. They have 31 spline axles and would be the right width for your B2. and if you dont want to do a solid axel swap up front I would also suggest the Dana 35 out of the explorer if pretty much a strait up swap and a lot stonger than the Dana 28

heres mine

also psot up here, no better place for info on RBV's
http://www.broncoii.org/fordforum/
http://www.therangerstation.com/foru...on.com/forums/


for cost relability.....buy a 91-94 Explorer with a manual
swap in the 4.0L, D35, 8.8 and manual trans

its all virtual bolt in, D35 bolts right in, 8.8 needs spring perches welded to top of axle tube, the engine tranny fit in stock B2 mounts just need to be rewired

if you want to run a auto then find a 82-85 2.8L ranger/B2 with a C5 (strongest auto to fit ford V6 bellhousing with any adapters

explorer sports are basically the same as a B2 with about 3-4 inch longer wheel base, but have all the stronger goodies

I'd go with an 8.8 before the EB 9"- higher pinion for your short WB, and the early Bronco 9 is 28 spline and more expensive. Also, the EB D44 has the small D30 sized u-joints in the axleshafts. A pair of Scout or Waggy D44s would work better, but any solid axle swap will take some work up front.

Stick with the 4.0L ford , FI instead of a damn carb , they came with automatics behind them which will be easier to wheel and easier on parts . Lots less impact with an auto tranny .

Just build an explorer , it will save you a lot of time as all the parts are in it or if you really want the B2 body then swap every thing from an explorer into it .

Thanks for all the input, I'm wondering if anyone has any inside on weather or not a Dana 44(coil) out of a 1979 F-150 will work as a front axle? And what rear axle is in the same truck (1979 F-150) and if that will work for the rear of the BroncoII?



*After doing some reasearch I found this "all the 78-79 f-150 4x4's and broncs had the 31 spliners"

front are too wide, and rears are 9 inches.
