OK, does anyone know where I can find a decoder for a rear axle tag? I'm looking at a possible 9" to buy online, but the numbers are very hard to read by the pictures. I've asked the guy to look at it but he says he can't read it. Supposedly it came out of a 67 mustang and from what I can see it looks like it reads: 1st line--JES-F 2nd line--300 8LE 933. I understand that it's an open diff with 3.00 gears. But what does the rest of it mean?
