Both hydro and mech clutch versions are available, I actually have one of each.
The early ones, particularly 4wd, seem to be mechanical.
For most of these the pattern on the bellhousing is unique to this trans, although there are some that apparently have the Chevy pattern.
To check you have the correct bell, line up hte pattern. Then check if the front bearing retainer just slides into the bell. This is larger than the Muncie / Sagniaw GM front retainers and the bell should just fit it. This is critical to the alignment of the trans.
I see you got the shifter, that's the other critical part.
