    Questions about a \'70 C10

    My buddy has a 1970 2WD C10 that we're thinking about converting to a 4X4. I have a couple questions.

    He has a 4 spd Muncie (w/ granny). Will any type of t-case bolt up to this tranny?

    He has a coil spring setup in the rear. Does this truck use the same frame as the leaf-sprung 4WDs? Just want to see if we can convert the rear to a leaf with no problems.

    Different frames. 3/4 ton(leaf sprung) and up and 4x4 frames are the same. Some Chevy 1/2 had leafs as well as a larger number of GMCs from 67-72. Any divorced TC would work, it maybe cheaper to find a 465 with a TC already attached as you would have to still get the correct output shaft and adapter from the tranny to work with what ever TC you find.

    the trannyh will not bolt to a trqansfer case input because the 2wd trannies have an output yoke for starters, totally different output design, you need a 4x4 one or converyt yours to 4x4 with a parts 4x4 tranny(alot of work)

    67-72 frames were two basic "designs"

    1/2 and 3/4 ton could be straight 34" wide rails in rear or could be bowed out to 38.5" directly over axle and then back to 34" for bumper brackets, bioth designs used G70 leaf type rear suspension, you can put 67-72 leaf rear on a bow out coil frame as factory did alot when g70 was ordered on a 1/2 or 3/4 ton 2wd BUT you cannot put coil rear on a 34" straight rail leaf type frame as it is not wide enough for the coil rear crossmember directyl above axle for the upper coils retainers. you can use a coil frame for leaves rear but isnt what factory did for 4x4 builds, they used a 34" straight rail frame such as all 4x4 blazers and longhorns(all were 2wd) and 1 tons(all were 2wd) frames were

    converting a 2wd chassis to 4x4 is ALOT of work and you would need a complete 4x4 chassis to get al necessary components to make it 4x4, you would be better off to just get a 4x4 frame or chassis, you will have to modify front rails for the front rearmost hanger bolts to pass through rails and swap body radiator support frame brackets to 4x4 style, will have tgo cut rivets to do this.
    converting a 2wd chassis to 4x4 is not a simple bolt togetehr affair and is not what factory did, they had a whole different frame made for 4x4 applications

    good luck
