Sad to see this in the junkyard

LOTS of good parts on that, and most will work way back down into the 1960's.

be careful with the wheels as the spare was 15x6 and has likely replaced one of the main wheels without being noticed.

I've never seen a 5th Ave with a thermoquad. Likely added.

Most all of the cruise control can be fitted on any Mopar.

"Police" style steering box
Electric trunk release.
Disk brakes
Sanden AC stuff
9.2:1 318 with 302 heads
Lockup 904/999
6 way power seat track
Bucket seat nuts and large captive washers that eliminate the need for inboard floor reinforcement plates
Dash lights and switches
Power window motors
8 1/4 that fits in an A body with only a perch move

ETC

School me on 302 heads. I know they are a huge improvement over standard smog 318 heads but do they really help 360s? They bump up compression but the ports are also considerably smaller? Is there really anything to gain over standard 360 heads?
It's just bad timing for me, I likely won't have time to give it a good visit in the junkyard until next Saturday at the earliest. I wish I could pull the entire drivetrain.
I did take a peek into the trunk and the carpet looked like it had never been touched and had the original space saver mini donut in there. Looked to be about 15x3 with a bicycle tire on it
