What do I have?

[Manitobamudman]

Im totally new to Jeeps and have no idea what I have in this truck.
Its a 76 J-10 Jeep truck with a 4.2l I6 with a 3spd manual transmission and a manual shift transfer case.
Can anyone tell me from experience:
What axles are under this truck?
What transfer case I have
Will a 318/360 bolt up to this tranny?
Will a GM or Ford motor bolt up to this tranny?
What transmissions will bolt up to this transfer case.
Sorry for the absoulte nooblet post but im totally lost when it comes to Jeep/Chrysler products.
Thanks in advance.
Also I might be able to locate a vin of some sort.

[offroadjunkie]

a vin number would be a huge help for the guys that know about these trucks... it tells you exactly whats in the truck. Also if you buy a red star and post up some pictures of the drivetrain im sure people will be able to help you.

[Manitobamudman]

I can probably get numbers off all the parts.
Its just that that Jeep is at the farm and I'm in town.

that is the best guess as to what you have.

The Dana 20 is a cast iron transfer case, having a passenger-side front output and a centered rear output. It has the same "Texas" front mounting input flange as does the Dana 18.

that should get you what else you need.... Canadians

[Manitobamudman]

Sorry I'm new.
How strong is the dana 44 and amc 20?
What would be the max tire size you'd recommend?

[crashnzuk]

No Chrysler product engine will bolt up to this set-up without an adapter or modified bell housing. AMC stuff is NOT the same as Chrysler stuff. You can put damn near any engine in front of any trans if you spend enough time or money. Personally, I wouldn't waste my time adapting a 3 speed trans to anyting. Use the set-up as-is or get something entirely different.

[Manitobamudman]

well what v-8 would be a direct bolt up to this transmission?
or what tranny would directly bolt up to this transfer case.
thats more of the question

[crashnzuk]

Any AMC V8 form 70? up will work with the bell housing. I would imagine any trans that accepts or can be adapted to the texas pattern t-case would work.

[Manitobamudman]

what chevrolet trans would fit up to this transfercase witohut an adapter?

[kingmick217]

Chevrolet Model 20
A version of the Dana 20, though rarer, found its way into 1969-1973 Chevrolet Blazers. They were much less common than the NP205 and NP203. We have seen one Dana 20 in a Chevrolet truck with the TH400, but there is no documentation to support this being a factory combination.

[Manitobamudman]

hmm
i wish i knew what the hell i was talking about then I wouldnt look so dumb
Is there a chart with adapters or something that I can look at?

[kingmick217]

Just click on this link and you will find the info you need.

I don't like using adapters and crap myself either, but it does not apear you're going to have a cheap easy route. It may be better to just get a whole donor truck and swap the entire drive train if you have to go chevy.

[Manitobamudman]

its just that I have numerous chevrolet motors and trans kicking around so using an adapter would be very cheap for me if it ended up working

[Manitobamudman]

wow 620 bucks to convert the trans and motor to my transfercase
thank god that case is bullet proof

[Manitobamudman]

I think i might have a 150 according to this site?

here is my jeep finally lol

[crashnzuk]

I assume you want to ditch the 258 for more power in the mud? If so, you'd be better off getting a chevy trans/transfer case combo to go with your Chevy engine. You should have a lot of room in that J truck for nearly any trans/t-case combo. It would be cheaper and easier since there would not be any aftermarket adapting.

you are 100% correct on my purpose
wouldnt changing my drive train make me need to get new drive shafts?

Oh It will,

You can have drive shaft shop cut and balance it for about $50 a shaft.

[crashnzuk]

I just saw an AA adapter in the classified section that mates an SM465 to a Dana 18/20. Might be worth a look.
