[eds-fj60]

i am looking at the blazer it doesn't have a motor , all time 4x4 .
what i wanted to know is what it would take to make it a selectable 4wd .
i have a new 700r4 in my shop and ord sales and out put shaft for 160 but then i have to do the Doubler right .
what transfer cases is in it .
what do i need to make the trans work with the transfer case and what transfer case do i want .
i have a motor in my shop as well .
this is the add 75 GMC JIMMY, NO MOTOR, NO TITLE. 4 INCH LIFT, FULL CONVERTIBLE TOP, DANA 44 8 LUG IN FRONT, 14 BOLT 8 LUG IN REAR. FULL TIME 4 WHEEL DRIVE TRANSFER CASE, 4 SPEED MANUAL TRANSMISSION
just found this
spacer is used to put a 700R4 in place of a TH350, or to put an NP203 or NP205 behind a 700R4.
If you're installing an NP205 behind a 700R4, you will need this spacer, a TH350 to NP205 adapter and a 27 spline drive sleeve. for 75 still need the right out put shaft .

It should have a np 203 transfer case in it now.

What is your goal for this rig?

Would be easier to juat get a np208. Nice low range and you can fimd them all over with the adapter to your 700r.

PM sent

If you currently have a 4spd all you have to do is get an NP205 from behind an sm465 and bolt it in, then put some manual hubs on the front axle if they aren't already there and you are done and bullet proof. If you want auto pm me back!

Ford, Chevy, and Dodge all used the NP 203 transfer case in their AWD/4x4 trucks. It is a fascinating transfer case. It is the prototype that led to the modern chain driven and planetary geared transfer case. The NP 203 transfer case was gear driven though. It had high/low unlocked and high/low locked. In high/low unlocked the chain driven portion of the transfer case acted like a differenchial allowing the vehichle to be in all wheel drive on dry pavement. In the locked position the transfer case locks up as in normal four wheel drive operation for loose surfaces like mud or sand. The low range was 1.96:1 or 2:1. The good thing about this transfer case is that the gearing is all separate from the transfer case in a two speed gear box mounted in front of the transfer case.

So with that said, you separate the transfer case from its range box. Then the transfer case is scrap iron, and the range box goes between your transmission and a NP 205.

End of Story.

thanks thats good info.
i think i am looking at the offroad design 203/205. just want to do this once lol like anything we do is once .
was looking at these , looks like alot ?
Ford F350 4X4 axles, The front is Dana 60 Hiph Pinion with steering arms and track bar and bracket 3.73 gears, Rear is a Stering 10.25 with 3.73 gears, Both have disk brakes
Out of a 03 Ford F350 single wheel truck
Rear needs a pinion seal ($15. dollor part)
Would make great set for jeep, rock crawler, mud bogger,
$900.00

$900.00 is an average price for Super Duty axles. We actually sell them for that exact same price. They are definately a step up from the Dana 44 front and 14 bolt. One thing to keep in mind though before you buy your wheels is they have a 8x170mm bolt pattern.

I was going to do the NP 205/NP 203 doubler. For the same money I can get a NP 205/NP 241 doubler. The NP 241 uses a planetary gearset instead of a gear box which is lighter and has a 2.70:1 low range. This kit is avalable from Offroad Design. I am pretty sure I am going this route.

Absolutely avoid those axles, you'll have to change LOTS on your truck to install them and you're still left with unit bearings, ball joints, you can't attach steering to either knuckle (which you really need to do) and a bolt pattern that is very limited and expensive to get wheels for.

For that money you can almost find a set of GM 1 ton axles which are what you really need (if you need a D60 in the first place, you didn't tell us tire size).

FWIW your 4 speed manual with a 203 on the back is a rare find

He already has a 14-bolt rear, so all he needs is the 60 front. The Ford front won't even have the pumpkin on the right side. Avoid!

Yes, definite oddball only even used for a couple years.

Somebody said Super Duty axles. If you found a Super Duty front end it would be a Dana 50 or Dana 60 and probably a high pinion. Either 8 lug. This is great if you are building a Ford. For everything else using Ford specific parts on a non Ford vehicle is way out in left field. Chevy is more adaptable and often times cost a fraction of its Ford counterpart.

I have a Dana 44 HP on my Bronco from a F-100 and I am getting 8 lug outters for it to match my Dana 60 rear. For what its worth I think you have a nice set of axles. The rear end is choice and the front end is fair until you start breaking it. If you don't break it then it is not worth upgrading. If you do up grade I would get a Chevy Dana 60 or a Chevy/Dodge right hand drop Dana 70.
