Zombie Dart! '72 Dodge Dart
If I'm not mistaken, the plugged line in the fourth-to-the-last picture is an A/C line and won't affect how the car runs. The one spliced into the hose that runs from the PCV valve won't affect it, either, as long as it doesn't leak. Even then, it'll be negligible if your crankcase ventilation system is working properly. I'd spend $1.50 on a foot of hose and eliminate the "T" in the line.
I don't have wheel cylinders for the front end. New ones for 10" drums are pretty expensive compared to the rear 9" setup. Advance Auto sells rebuild kits for 10" brake cylinders for less than $4 a set (for some reason they're cheaper than kits for the 9" brakes), and a brake cylinder hone is $11. Spend an extra $4 on bleeder valves, just for good measure. You'll use brake fluid for cutting oil with the hone. Bickity-BAM! You can stop your car!
PM me your address and I'll send the wheel cylinders for the rear on Tuesday.
Dorman's help line has trim rings for the headlights for $7 and some change, both sides included. The part number is 42408.
The headlamps themselves are Sylvania part number H6024 XV and are more than likely on the shelf at your local autoparts store. They'll run you about $16 a pop. Dorman Help! also has adjuster screw/nut setups for a couple of bucks.
