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 ! 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 !!! 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.
