Can anybody with factory r/d lock (4.9), confirm the following:
1)Factory Sticker on the rear of the diff housing "G R C 4.900"
2)Right Axle No. " 58 "
3)Left Axle No. " 57 "
4)Behind the wire switch (on the center diff.) there is a number," 16 "
5)Under the pinion (on the center diff) there is also a number, "5E22"

Any help will be appreciated,

Hi Raspas
I don't know about the rest of your query, but the axle numbers on my 4.9 locker are as you say.
