Rpo codes

Some of those links did not work but I got a good link over in my thread about best and worst years. A question about the codes tho...
I read somewhere that the G80 was a POSI type rear end a G20 was a locker. The RPO code attachment I recently linked to refutes that and says a G80 is a locker. Are these true lockers or a corporate change by Chevy from the 12 bolt Posi rear ends? G80 was the option according to the booklet but I could not find a G20 code. Most of the stickers in the glove boxes that I have looked at are the G80 codes.
Going to look at one next week.
Thanks again.

I did some research myself and apparently the G80 code changed sometime in the 1980's to the locker. I found it on the Eaton web site that the G80 is their OEM locker. I also read that if it engages too hard it has a tendency to fragment. It has a nick-name of "Grenade 80".
