I need some info on a bell housing

Sure they used them in vans and light trucks. Last? summer before last? I was hired to assemble an A833 OD with a MARRIED transfer case adapter for a CHEVY. They made these both with Mopar and with Chev bolt patterns, some therefore used in Chevs with an adapter plate

A833 in GM trucks?

Near as I can tell the gearbox cases (for GM) came with 3 different setups

(Some were cast iron, some aluminum)

1....Mopar bell pattern with some sort of adapter to GM bellhousing
2....Mopar bell pattern with a GM built bell with Mopar pattern
3.....Special gearbox main case with GM bolt pattern

Not sure, most photos I've seen had special GM input shaft and special GM tail housing.
