Rosie is a good looking girl.

Look on top of rear end diff, you should see XN-xxxx, a two letter prefex plus four #'s.

XN or XR = 8.10-6.13 gear
XS or XD = 8.86-6.70 gear the four number will tell you the date of Manufacture

You are lucky to have the shifter...I've been looking for one a for couple of years.
