1970 transfer fit in 1974 scout

[wkdscout209]

My Scout is two wheel drive that I want to convert to 4x4. It doesn't have a front axle or doesn't have a transfer case. I found a 1970 Scout at a salvage yard and has the transfer case front solid axle with locker hubs and rear solid axle.? Can I use any of this? My Scout is a inline 6 with a 4 spd manual tranny. The salvage Scout is a '70 w/ auto v8

Could some of that stuff from the 800 be made to work? Yeah, perhaps a little with considerable hassle. You'd be money and time ahead imho to source your parts from a '74 or newer sii preferably with manual trans. That way you get Dana 44 axles front and rear with discs up front and matching gear ratios which is essential. You get a Dana 20 transfer case with the correct gear pitch angle and bull gear, and you get a transmission with the adapter housing to marry the t-case to.

Kool thank you. So I would be better of finding parts off of 74 or newer scouts. Are all newer 4x4 Scout equipped with the Dana 20 transfer ?

All Scout II 4x4's produced from 1971 through 1979 came with either a d20 t-case or in rare cases a single-speed chain drive unit (best to avoid these). Some early 1980 models also came with the d20 while others came with a d300. 1974 was the first year that d44 front axles with disc brakes became optional equipment, before becoming standard in my '75. The t-case in that '70 800 you were asking about is also a d20, but with a slightly different gear pitch angle than you'd likely find in one from a say '75 sii for example. As long as the pitch angle between the trans and the t-case match up, no problem. If they don't, you get excessive noise, vibration and accelerated parts wear. The project you're proposing is not like reinventing the wheel, but there's a lot to take into consideration. You really need to immerse yourself in the tech threads on this and other forums. Read about axles, t-cases, trannies, etc. What makes your situation a bit more tricky is that amc six-banger motor. It has a completely different bell pattern than the IH sv8 and 4 poppers do. There May also be differences in transmission input/output shaft length between amc and IH drive train assemblies. Ideally, if you could find a '74 or newer 4x4 model Scout originally equipped with the I-6 and 4-speed, even if the engine and body were shot, who cares? Swap the engine and body from the 4x2 over to the 4x4 and be done with it. Then there's the axle drive shafts. You'll need one of the appropriate length to turn the front axle. Will the rear shaft you have now be the right length when you swap in the 4x4 components? Kinda doubt it. See what I'm driving at here? This deal has mushroom effect written all over it. It won't be just a simple matter of sourcing a couple random parts and slapping it all together in one afternoon. You're talking about a hefty project with lots of (hopefully) correct parts to gather.
