I looked AGAIN for my axel codes, and according to my Haynes book, my #'s don't mean jack. On the left of the pumpkin was (6 or G)7890 and on the right was H270. The book says to find the # on the right side of the axel tube about three inches from differential cover---This is right, right? Is the right the passenger side or the driver's?

Here's an example of a code you should find:
CB G 218 D E
CB = Ratio
G = Plant
218 = 218th day of year
D = shift
E = Positraction Source
It should be on the passenger side of the rearend. Give it a good cleaning with a stiff wire brush, see what you come up with.

Take a piece of sandpaper and go over the passenger side axle tube THOROUGHLY. I had to wire wheel the axle on my Z to find it, and even then it was lightly stamped and hard to see.

scrub, sand, wire brush HARD, ~3" from the differential on the FORWARD facing side of the passenger axle tube.

So it is on the side opposite the differential cover, on the side with the engine, as opposed to the side of the trunk? I will look.

Numbers are very hard to see on the older cars. On the axle tube near the spring on the front of the tube is where mine are. Your Casting number on the case, the H270 would be probably Aug. 27, 1970. Best bet all around is to remove the cover and read the tooth count on the gears. Never hurts to change the lube and you'll know for sure if there is a positraction in there.
