I found out by word of mouth over the weekend about this 1972 k30. It is not in mint condition (paint faded), but is 100% rust free and has been in a garage parked for the last 15 years.

I am on the road all the time so I have even less time to drive far out of my way to take a look at it, or even know if it is worth while. I am a sucker for that body style and can pick it up for probably a few hundred.

I know that the front axle is drum brake, well told it was drum brake and am confused because of the research that I did it looks like they quit that in 71 but not sure. What axle would it be, and the rear for that matter. I did read through the 60 bible and understand chevy didn't start using the 60 till 77.

Also what motor and drivetrain were these most likely to come with? EDIT: I found out what motors and tranny's, but no info on the transfer case.

thanks in advance.

Unless the front was swap for something else, the front will be a Dana 44.

The rear, probably an Eaton. Similiar to a 14 bolt.

Motor and transmission, what was the options for that year, IIRC anything all the way from a 307, 350, 396, 400. What else?

Any idea on a t-case. I seen that they had many different trans options and motors as well on wikepedia(sp).

I am ass uming that it would be a closed knuckle 44 as well. Probably not a big aftermarket for the rear axle I would guess either.

Well I was hoping for the best, but if the body is as good as I hear, I may just have to go and take a look, and swap in my 60.

thanks

Most likely a 205 transfercase. That is what the 68 to 72s I have had all came with. (4 of them)

It SHOULD be an open knuckle D44 but if you're sure it's drum brakes then maybe not :confused: I was pretty sure that by 72 they had gone with front disk brakes but maybe that's only for 2wd?

Considering they "technically" didn't make a K30 in 72, that'd be a find. If it's a drum brake front, it's 70 or older. I am assuming they are saying K30 cause it has 8-lug axles which according to some people makes it a 1-ton. Front is probably a closed knuckle D44 if it's drum brake. Rear is probably an Eaton. T-case could be a 205 or Rockwell.

My 72 had disc brakes, I thought that they stopped using drums on the front in 71.

my buddys 69 gmc came with a small block, sm465 and a rockwell t case. not to sure on the model of the rockwell, but its a beauty, gear driven and looks as beefy as a 205, but the coolest part is the outputs are dropped. he has a 6 inch lift and no driveline angles whatsoever.

As others have said, GM did not make a one ton 4X4 (K30) in 1972. The only possibility of an "original" truck would be a Napco conversion and I am not sure what front axle was used in those (probably a 44). Front disc brakes were standard for GM light trucks starting in the 1971 model year. Also, the only t-case used in GM light trucks in 1972 was the NP205.
