AMC ratio ID help

I just brought home an 80 CJ7 organ donor and went to ID the axles. The front D30's tag is unreadable. The AMC20 rear has a letter I can't identify, a "Y". Its not on the chart on the tech pages. Before I do a tooth count does anybody know? Thanks in advance.

Yes, if you notice, "X" was also left off the chart.

Y is 3.07 gears with a Trac-Lok and X is 3.07 and open. The Trac-Lok was optional, but the 3.07 gearing was standard in 1980.
