Presumably, USCT is answering their phone or email, or has the dimensions on their website, but that may not be the case.
Cab, that's to lift the front of the car using an engine hoist:
Top bar is hooked to the hoist as a crossbar, lower bars mount to frame rail bumper bracket holes & slide into top bar.
I would think USCT is smart enough that it fits any unibody Mopar; note various attachment holes.

Some guys make their own, and it's a common method if one lacks a lift.
