[rcamacho]

M1151A1.
Removing rear diff for service. The driveshaft to pinion bolts are stuck well. Tried WD40 in the back side of the bolt hole bores along with mapp gas heating. No joy.

Trying air hammer flat anvil on the pinion next. Then destructive removal.

Any other suggestions?

Dang, when I built the DuraVee the largest yoke I could find was the 1330 series, now I see them in 1350 series.
Not that I have been able to break the 1330 series U joint
The early trucks like the M998 used a 1310 series U joint.

My hero today.
Some close throw shaking on the yoke casting around the bore and very carefully on the bolt face did the trick.
