Ok Lenny i took a look at the diff last night and this is what I came up with. The input shaft has 27 splines, and the output shaft (axle sides) have 32 splines. They do turn together when I turn the input shaft. I marked the starting point with a grease pen and turned the input shaft two full revolutions and it puts the output shaft over it's mark by 3 splines. Meaning it went over it's starting point by 3 splines. So does this tell you what I have?
Thanks
