Looking for no BS info on 8 1/4 rears

Dakota axles from 87-91? had 4.5 by 5 lug axles with the same 27 splines, 92-96 the axles were 4.5 by 6 lug with 27 splines, 97-04 the axles were 4.5 by 6 lug with 29 spline axles, 05-? axles are 5 on 5 with 29 splines.

Jeep Cherokee is a better bet unless you find an old Dakota 5 lug axle.
