Need some electrical help with my ‘68 Plymouth Valiant 100

We did, thank you! Still eating turkey.

I hope yours was great, too!

I am NOT a price authority, and we have not seen the rest of the car (well, maybe you posted it somewhere else – I haven't searched), but that sounds like it's in the "reasonable" range for a running, driving car, without major destruction (big rust holes, raccoons ate the interior, etc.).
I'm of the age where any price over $500 for one of these just seems crazy, so my subjective opinion has no value.

Probably the best way to go, and if you're lucky, or if they're nice, it won't cost too much.

I can only answer this for a Slant-6, so I can't suggest anything specific.
I can say, though, that the spark plug discussion can get like the oil discussion, so you might want to make a new thread for that.

In a non-high-performance application, the exact plug brand probably doesn't matter, so long as the heat range is about right.

My question would be: Why do you need to replace the plugs?
Are they totally worn out?
Are they dirty? Do they have thick leaded-fuel crusting?

Odds are, the ones you've got are fine, at least for now, if you clean them (wire brush and some lacquer thinner) and re-gap them, then go for a good long highway drive.

Aside from physical damage (chipped or cracked insulators, bad threads), so long as the electrodes have fairly sharp edges and aren't rounded, they should be fine.
I'd wait until things are more together, gather more information, and decide then.

All of that being said, I must admit that when I got my current car, I immediately bought new plugs, as well as wires, cap, rotor, points, condenser (all 4 old stock Blue Streak), belts, hoses, thermostat, carb rebuild kit, fuel hose, valve cover gasket, air cleaner, oil filter, oil, trans gasket & filter, ATF, rear-end oil and gasket, brake cylinders, master cylinder, rear e-brake cables, spring kits, adjuster kits, front wheel bearing seals, and I disassembled and re-lubed my universal joints, so I'm no a sterling example of conservatism.
(Of course, the car actually did need all of that stuff after sitting for so may years.)

Glad to hear you’re still enjoying the turkey! We have a carcass left that I’m saving to make some yummy bone broth soup with. Gotta make use of it all!

The interior isn’t the worst, but it’s got some big tears in some areas. The headliner needs to be redone badly too. I’ll probably do the upholstery on the two benches myself and have a professional do my headliner. Those seem tricky and I don’t want to mess it up. There is very minimal rust on the car. Most the rust is in the trunk due to rotted weather stripping and a small crack in the trunk (not from rust), looks like someone may have hit the car and caused it to crack on the inside seam.

Well, multiple other problems have come up with the valiant, which is why I’m needing new spark plugs. One of the distributor cap clips is broken off and it’s apparently being held together with a zip tie…thus causing it to misfire. So just going to replace the spark plugs since now having to replace the distributor.

The motor mounts are rotted, so while he is doing the intake gasket manifold he will put new ones in, along with a transmission mount, the alternator belt isn’t the worst, but it isn’t amazing, since I’m having to take all of it off I’m just replacing it since it doesn’t cost much, the alternator doesn’t look too great, so I did buy one just in case. My uncle is also sending my another alternator he got from a 70s dodge dart. Unsure if that one would work in my ‘68 valiant. But it’s free. I guess I could probs lay return the one I bought if it fits?

Radiator hoses/water hoses don’t look or feel the best, so I bought replacements for those. The voltage regulator is definitely shot so I did buy a new one. Also the coil resistor is no good, so got a new one. There is a possibility the the rear wheel cylinders are bad and for sure the front brake hoses are rotted. I ended up buying shoes for the front and rear along with new cylinders for all four.

Really hoping there aren’t further issues, but that’s what to know as of now.
