not really a way to visually see. pk number on the side. google the number or take the number to your mopar dealer.
The 42RH is physically longer due to the OD in the longer tailsgaft
This sounds rather definitive. Is this located near the shift bar?
Some time the NSS will have one so make sure it is not that.

Well, that big old overdrive tailhousing is your first clue that it's a 42RH...

NSS points outwards nearly horizontal, the OD connector is vertical, mounted on the "shelf" of the casting
Ok so this is not 42RH

Looks like a late A999 with a lockup torque convertor.

Would the A999 have the 5 banded clutch set up and heavier drums?

Yes, it should have 5 clutches, heavier bands, a 4 gear planetary, and the low first gearset.
