That takes skill! The only one I have ever seen broken internally had the syncros moded by cutting off every other tooth for speed shifting. Not mine. On my 465 I did have to install new sintered bushings. That was In the same truck as the 12 bolt that I tore up. Considering I torqued it enough to bend the floor pan on more than one occasion I am surprised that I never broke the mount bolts. Always driveshafts, axle bearings, or ujoints.
