8 3/4 woes
and if you broke it in 1st gear with a 727....check the sprag in the trans....otherwise the trans could explode....
yes..rebuild the 8 3/4...and in a few years replace the ring gear as sooner or later they break...check the sprag again...rebuild 8 3/4 ....OR
Buy a Dana S60......and be done with it....JMO
