Good info Jerry.
Got to spend alittle time on the Jimmy today. Pulled the front clip to get better access. It had been off before so the bolts came out pretty easily but it was missing a few..... Found a few bad spots but nothing major. Got the engine ready to pull, gonna pull the engine and tranny as a unit.

Took a few pics of the 250's motor mount setup, perhaps those thinking of a 230/250/292 may find them useful.
