[68Timber]

I've got the same serpentine kit to put on my 383. My truck already has a V8 so I'm good on the radiator and shroud but I'd planned to use a fan and clutch from an 88-98 truck as those are serpentine, just pointing out a possible option.

I don't know for sure the difference between AC and non-AC shrouds, but the lines do run across the top of the shroud, maybe it's attachment points for the AC lines. I haven't had a non-AC truck to see if they're not there.
