OK -
There should be a total of six bolts thru the bellhousing, and the bottom two retain the inspection plate and have nothing to do with the engine. The other four are located with one on each side below centre (easily visible from underneath,) and two at the top rear of the engine block (just below the cylinder head parting line.) The top two tend to require the use of an E12 external Torx socket, but are threaded 3/8"-16 and are easily replaced. Replacement is recommended for future simplicity.
There should be either two or four bolts at the crossmember, tying the mount cushion to the transmission case proper.
There should also be a total of six studs at the transfer case adapter, tying the transfer case to the transmission. IIRC, these are all threaded 3/8"-16 as well.
This help?
