I thought I saw that cap/plug for A.I.R. when I first saw the listing. I just now went back and found it.
I have a write up to talk about the A.I.R. ports as well as caps (once I get a chance to finish it).
I “had” a handful of that same part – but they have all disappeared. I have what I need to make some and gaskets – but hadn’t gotten that far yet.
Note: if anyone sees one of these plugs in auto salvage or online, get it! Chrysler quit selling them in ’89 or ’90. They are found more in pickups than in cars.
The gaskets for them are also hard to find – so was thinking of also making some replacement gaskets, as well (just another thing to put in my “to do” list).
I don’t know why but pretty much every Chrysler made until the mid ‘90’s, including Front Wheel Drive cars, had black plug wires and a orange coil wire.
The exception was a few performance models had all orange wires.
I do not know why.
The coil wire on my ’77 wagon is still orange.
