I just got my '68-72 2WD gearbox from LMC Truck for my crossover steering set up and I want to make sure it's the right one (2WD vs. the 4WD unit).

Does it use the same/similar housing as the 4WD unit?

Can anyone post some pics of each?

The reason for this is I'm currently dealing with a screwed up order from a few weeks ago with LMC Truck and I guess: 'A burnt Dog Dreads Fire'.

I just want to make sure I don't bolt the thing up, get the fluid in, purge the air bubbles, only to find out it's the wrong one!

Thanks guys :D !

UPDATE (Dumb) QUESTION:

I have a '72 CST K5 Blazer. What year(s) 2WD PS box can I use for my cross over steering?
The reason why I'm asking is because after getting info from you guys, I checked my PS box that LMCTruck sent me and the sector shaft is as described.
HOWEVER! When I looked at it I noticed that when I positioned it as it would be mounted, the mount tabs were on the wrong side :mad: :( !!! Like a Ferd PS box would be. WTF?!
Are there any Chevy PS boxes mounted like Ferd's would be (on the inside of the frame rail)??

Thanks guys.

A quick way to tell buy looking is the 2 wd pitman arm shaft will have teeth cut atw around it, except on four sides 90* apart it will apear that the valley of two teeth didn't get cut, this is for 90* clocking of the pitman arm shaft.

The 4wd shaft will have a slot cut out (perpendicularly??? I think thats right $$the spelling$$$) to the shaft about .375 about 1/2 way between both ends, on the opposite side of the shaft, a 1/4 of it will have teeth cut on it. Sorry no pics i'm at work.
 
in simple terms... on a 4x4 box, the shaft is splined part of the way around it, and on a 2wd shaft, there are splines all the way around the shaft with 4 "keys" at the 12:00, 3:00, 6:00, and 9:00 positions.
 
I was wondering if the pitman arm shaft out of a 2wd F**D '79 RV would fit in my '79 k25 4wd sterring box, it appears both boxes are siginaw, the F**D box is inside the frame, while mine is outside framrail. wondering if anyone has done this or im pssn in the wind.
 
an s10 steering box is the same size as a full size box, but they mount on the inside of the frame. maybe thats what you have.

post some pics of it and we could help identify it.
 
If you have flare fitting lines you need any TRUCK 2wd box from 1967-1979 or 1980 first design. The CAR box mounts on the inboard side of the frame rail.
