WTB higher gear for 8.25

There is a certain year where the spline count on the spider gears goes from 27, like the late "A" bodies to 29. As stated by other responders all carriers in 8.25's are interchangeable. I've pulled many gear sets from junked Jeeps and Dakota p/u's for folks from the local junkyards here for use in "A" and "F" bodied cars and all have installed well.
