Driveshaft slipyoke compatability?

[rangerbum]

Hey, i was wheeling and ended up snapping an ear off my slip yoke on my rear driveshaft on my 85 b2 (double cardan style shaft). I have a 92 explorer for parts, i know the whole shaft is too long, but i could just swap yokes if they match. Are the splines the same size? U joints?

Tried it this afternoon, the explorer yoke has larger diameter splined section ang thicker splines as well. Will certainly not fit. However the front driveshaft is the same length as the b2 rear.
