There is a lot missing from the sway bar thing in the tech library:
theres no ac compressor or condenser and there are lines coming out of the evap core going into the fender well. never seen that before.Looks to be pretty decent based on the one pic lol.
Whats weird about the AC? Im gonna guess its a dealer installed unit rather then a factory installled.
Best thing you can do to the 2.8 is get rid of the feedback carb/eec iv garbage and swap it for an early carb/duraspark setup.
