My First Mopar- 1966 Barracuda project

with the longer slip yoke you used, do the internal splines go right to the end? many of the longer ones don't, just giving a better support in the tail housing bush. this can mean only a short spline engagement though, in your pics the yoke looks quite a way out of the trans'. a simple spacer at the axle pinion will give more engagement and i'm pretty sure they're available through 4x4 suppliers for (modified for offroad) explorers.
neil.

Thanks, I’ll look into that. The internal splines don’t start right away, but the output shaft extends past the rear outer seal. The yoke is 1 1/4” from bottoming out but it looks like 2” exposed.
