One way to determine posi is to turn one of the rear wheels by hand and see if the other wheel turns in the reverse direction. If that happens it's not a traction Lok rear. I think you can determine a rough estimate of the rear gear ratio by turning one rear wheel one revolution and counting how many times the drive shaft or pinion shaft turns. If the drive shaft turns 3.55 times you have a 3.55:1 ratio.

Hope that helps,
