Tom,
Speaking of rebuilding the Butler JAG rears---it might be time to get mine up to spec. Do you have any leads on good Jag-rear rebuilders--nationally? I heard there's some outfit in Tennessee. If you don't know of any east of the Mississippi, maybe you know someone who does. Also, what did you have your guys do/replace? I suspect that my rearend is not "locked" and don't know the health of the gears and guts.
E-mail me if you want:
