Then, it doesn’t sound your too far away
-power steering conversion (was optional on 69 383 cars)
-classic air. Look at other Mopars with the conversion for hose routing ideas. You go through the heater blower plate. The new blower motors is in different place so you can use that as a pass through and place to mount expansion valve, etc. Don’t focus 100% on 383 A-bodies. B/E-bodies sneak the hoses through the alignment access plates/rubber behind the shock tower. I’ve seen some Hemi A-bodies with classic air. Check those out.
-if the seats bother you, look at modern seats as a core with customer seat covers with the same stying cues as rear or OE seats.
-if noise is issue, go back and add sound insulation. Under carpet, in doors, behind rear interior panels. Make a new rear access panel from special sound insulating plywood with sound insulating mat. That stuff is not seen or unbolts.
