Hey hey!

I would appreciate teh feedback on my new rig - I would like some ideas as to what will work and what wont.

Project: Rangie 2 door - uted and bobtailed inc chassis rails.
Diffs: GQ sourced and setup
Engine: Will be the 4.4 rebuilt with mild cam and extractors
Driving: Mix of hard fast cannonball style stuff and a decent amount of Krawling about!
Weight: As long as whatever we use is centered I'll be happy.

So with these things in mind - an auto or manual matters not - as long as teh output can be mated to the diffs - woo hoo!

So - in short - what combo that WILL work idea can you supply? I have access to GQ gearbox/transfer but am open to suggestions.... Namely your!!
Please fire away!!! :lol:

i'd use the GQ transfer, they are a solid unit, but the GQ gearbox would be a pain to work with if you are building the truck at home, they are fawking heavy and big. TH400 or something similar can be mated up to the datto t/case easy enough. That can also be slotted up to the 4.4, I believe??

Go the T-7004 Gearbox mated to a divorced NP205. That way you can find a 2WD one. You can pick up NP 205's pretty cheap $250-400.

Thanks Stu - but why a Ptrol - I don't want to be a number - I want to stand OUT!

Cool ideas so far - the car will be hitting a shop to get the setup done - so gearbox weight wont be too much of an issue.

How much is a TH7004 worth? What is the NP205 out of?????

Info info inof.....! :D

The New Process 205 was also used extensively in GM, Ford, and Dodge. GM and Dodge used the 205 in some trucks into the early 90's, Ford stopped using the 205 in 1979. The 205 is a part time 4wd 'case, meaning when it's in 2wd the front driveshaft will not receive power. It has 4 stock shift positions, 2wd Hi, 4wd Hi, Neutral, and 4wd Lo.
NP205 cases had several different configurations with Ford and Dodge using both married and divorced models and GM using many different input spline types and 2 different bolt patterns.
The NP205 is identified by several features:
1: The transfer case is one piece of cast iron. There is a short bearing retainer/output housing at the tail of the case, and aluminum bearing retainers/seal retainers at the front and rear outputs but the working parts are all in a single iron housing.
2. There is a small idler shaft cover on the back of the 205 with 3 small bolts holding it on. This is somewhat unique among transfer cases.
3. The overall length of the NP205 (in fixed output yoke versions) is about 12-13" from the front of the case to the center of the output yoke.
4. The shifter is a very simple lever operating a crossbar between the two shift rails that plunge in and out of the front of the case.
5. The ID tag is found above the front driveshaft output, and will list model, manufacture date and gear ratio.
