A little off subject \'67 C20

I am looking to buy a '67 Chevrolet C20 4WD truck. Does anybody know what front axle it has? What about the Tcase and trans? The rear end looks a little odd, it looks alot like a big 9 inch ford rear with full floating axles. Any info would be great.
Thanks

<font color=blue>If it's a c20 than it is two wheel drive. The rear is an Eaton drop-out. you can get lower gears and a detroit for it, but otherwise, I know nothing more about it except for the fact that it is really rare.</font color=blue>

It is a 4WD. I guess I should have said K20. Can I get higher gears for the Eaton like 3.55 or 3.73's? What kind of Tcase is in this truck?
Thanks

<font color=blue>I think it is an np205, but i'm not sure. The frontend is a closed-knuckle d44. You might be able to get lower gears if it doesn't have them already</font color=blue>

It doesn't look like a NP205. I have heard bad stuff about the closed knuckle design. Is this true? Actually I want higher gears instead of lower.
Thanks for the info.

They used a Rockwell T-case in most of the '67 and '68 trucks. I think parts are hard to find for them. The tranny will be an SM420 or SM465. Reverse on the 420 is down and to the left. On the 465, it is down and to the right. Above replys on the axles are accurate, except that I don't think gears are available for the rear end anymore.

<font color=blue>They are a little weaker than open-knuckle axles, but they are sealed much better. Patrs are getting hard to find</font color=blue>

The transfer case is a Timken T-221. Parts are obsolete, but you can still get seals and bearings. Low range ratio is 1.94:1. The front axle is a weakish closed knuckle Dana 44. I say weakish due to the small bolts holding the steering arm on. The rear is a drop out used from 1946-1972. Gears are obsolete, you may get lucky and find some.

Re: A little off subject \'67 K20

Well if I get the truck I want to put an open knuckle D44 or D60 in. I also thought that I would put a 14FF under the rear. I want to do this because I have heard alot of bad stuff about the early 4WD axles. Would axles from a 73-87 truck fit the '67 or would I need to find a 70-72 D44 and 14FF?
Thanks

Nope, the stuff you mention is a bolt in. Just measure the spring widths on the rear and front of that '67 and compare to the late model axles you buy.
