Looks like I have a front Diff Pinion seal that needs changing. Info I've gathered indicates the design changed in 1993. My 110 is a real hybrid and a daily driver - I was hoping to know the correct part # before I had to take the unit apart. Stamped on the differential casing is the number -RC1124. The dash is a letter I can't read due to the way it's stamped. I've also included a photo incase there was some external clues....
