Trying to identify A833 & shifter models

Just eyeballin here.

Looks like an over-the-counter shifter. That's fine but probably needs to be gone through. Looks like the holes in the shifter levers are the larger one so you'll need the bushings. If the trans is A-body then the Brewer's rods will work. That's what they do, Mopar 4 speeds. The reverse rod goes UNDER the mount.

I would buy a used factory crossmember (FABO wanted section) and use the stock style rubber mount. Looks like yours is solid mounted.
