Limited slips came in just about any year. The best way to tell if the diff is an LSD is to look where the spider gears go. One a 10 & 12 bolt, instead of seeing the spider gears, you will see springs and clutches(and a few other odd looking items)....

And as I learned the easy way... Look in the glove box for RPO code "G80".
no g80
isnt the code g80 for the gov bom and not a posi unit. and if so you dont want a 10 or 12 gov bom thay blow way to easy.

a G80/Gov Bomb is the only factory GM traction device used in trucks off the production lines.sweetk30 said:
According to the service and parts manual, you actually could get 3 or 4 different traction aiding diffs in the trucks.
Can't confirm, only thing I've ever seen is gov-lock or open, but I haven't seen every one out there.
G80 is a generic "traction aiding" rear differential code, used in cars or trucks, any type of limited slip, to include the gov-lock.

yeah!
except for the older clutch style posi, the detroit locker (no-spin), the power-lock (dana axles) and the track lock (dana axles), you are right.
in 67-72 trucks, G80 denoted a clutch style posi. I dont know when the switch to the gov-bomb was made.

when the fender tag says locking diff, does that mean limited slip, or a real locking diff?

Some have had bad luck with the Gov-loks. I would say get one and run it. See if you like it. I had one in the rear of my 82 for 4 years. Snapped a rear axle off in the carrier and it never failed me.
I actually thought about running a gov-lok in the 14ff on my Toyota.

To know if is it a FF or not, look where the wheel bolts on. You will have a set of 8 lugs that hold the wheel on. Then look inside of that at the portion that protrudes through the wheel. It will have bolts on the end of it. Thats a FF axle.
Do a search in the forum. There was a just a thread or two discussing what a gov-lok will look like in a 14FF with pics. And also explanations of SF vs. FF.

trac locs come in 8.8s too.
You have to pull the diff cover off.
Assuming you have a 10 or 12 bolt, if there are clutches and a spring (or springs) in the very center of the carrier (what the ring gear is bolted to) it's a limited slip. Gov-lock has clutches, plus some extra gears and weights that make it more complex.
You can put a limited slip out of a car into a truck axle (10 or 12 bolt again) but they aren't as effective off-road as a true "locker", as the trucks weigh a BUNCH more, (besides the amount of load placed on one wheel when off-roading) and weight is a disadvantage when dealing with clutch/cone style limited slip.
