AMC #4 another toy to play with

Ah, no your not weird, just do things different at times. As for drooling... The way you came off originally made me think you were dead set on them. Maybe it is you wanting answers more than anything. I guess I have to look back at times when I was not sure of which or what that I needed. Asking Qs can bring up a lot more Qs before making a dead set descision.  I just thought you were grabbing as much as you could that was available from dependable forum regulars. As I know enough to realize things are not as plentiful when being selective.

>> Where are the horns?<<

The way my brother talks - nailing the throttle might make a passenger scream loud..........

Obviously I'll want horns - I'll have to see if my salvaged horns work at all, they look like crap and have swelled in spots but may work until I get something else. I recently had to replace a horn on my baby Eagle as it started sounding like a sick cow so not sure if I have working horn or horns on the shelf or not.

If I remember correctly, and I did not think to grab the other papers while at my brothers place, it was bored .040 over

Will Scorpion rockers sit well under these valve covers?  I have a set in the box on the shelf-  always wondered if I should put them in the 390 in my 70 - now I think I know where they should go.

Holy cow, some more invaluable information.
Yeah, I saw that situation with the heater area - missing foam, and missing second heater core tube.
That's going to be fixed as I'll remove the heater box, put in a decent heater core if I can find one, new proper foam, and likely rebuild/restore the blower motor at the same time. That won't be a first priority, but on the to-do list for sure. That looks horrible besides not having any heat if defog of the windshield is necessary on our cool wet mornings here.

So INSIDE the car, there is a small wiring harness from the wiper switch to the rest of the wiring, but externally it's part of the main engine harness, correct? I knew it wasn't like the earlier Javelins as that wiring harness was soldered to the wiper motor, ran through the firewall and typically had 2 connectors that pushed onto the back of the wiper switch inside. That's because it was an option, and that's how the motor was wired up. It was bought/supplied as a wired assembly from Prestolite. Vacuum wipers didn't need any of that, so it was extremely simple for AMC.
72 saw the last of the Prestolite wipers with integral wiring harness.  The wiper motor sits to the passenger side, too, on the later cars, unlike the Prestolite which set over to the driver side.
I'm not sure yet how good or bad the interior wiring is.
I plan on going over there later today to put the seat belts in and I'll take another look then, maybe make a better determination of what all it needs since I won't have the real strict time restriction on me - although I can't take TOO much time, I'm supposed to be home ASAP for other duties and chores but still it should allow me more time to assess the needs.
Thanks for the added more detailed information.
Eventually I'll want a better grill, but for now this one is there and seems complete. It's just been repaired and the repair is OBVIOUS and in your face when you open the hood.
