Mopar OEM EFI

Sorry for the bump, but thought I'd try this again.

Went to the wreckers and had a look at a potential donor. '98 truck, 360 Magnum. Noticed computer to the passenger side, relay box to the driver's side. Wiring runs along the firewall, branches down behind the engine. Looking at taking the complete setup and everything on the firewall. Hope this will gather all the necessary parts. Also will take the accessories, serpentine drive, alternator, A/C compressor PS pump, exhaust manifolds, sensors, starter etc. Yard says $1200 for everything, they will pull, sounds fair to me. Am I missing anything? Any info on splicing the new accessories into the old Cuda A body systems, (A/C and PS). Can I use the late model exhaust manifolds? Any clearance problems with the FI manifold? I'm swapping my old /6 K member for a spool type from a 74 Dart V8.

I'd appreciate any help I can get here, thanks.
