I am a hobby seller on Ebay
I ran across a Cruising wagon in a local yard it was a rust bucket the side panels were rusted out so I grabbed the port holes and trim, the 3 gauge panel, the factory rear window louvers, and I puled the rear window with defroster with all the wiring and switch and relay, I left the glass because they wanted $80 for it and I was not sure what it was worth also I did not have a meter with me to check to see it it had an open circuit or not.
Okay now for the questions
(1) is the rear heated window conversion a desirable option? lets say worth $225 shipped to the lower 48 or $175-200 for a local pick up
(2) the factory Carlite portals with seals and plastic trim how hard to come by are they? Is $150 shipped a fair price?
(3) The Factory wagon rear window louvers were they held on at the bottom with allen head screws and nutserts how rare are they and what is the value of a set in decent shape needing repainted?
I have parted out my fair share of Pinto's in the last 10 years so this is all based on my experience with that and ebay. It is hard to sell large pieces of glass, especially on ebay. First of all nobody wants to pay for shipping. Second it needs to be packaged properly for it to survive the ride. I have never been successful in getting rid of all the glass from a Pinto I have parted. There is really not a lot of demand. I have a lot of it and I am going to keep what I need for my personal cars and get rid of the rest as I am tired of storing it.
With that being said, I am not sure if you ended up with the rear window glass or not? It sounds like you left it. Unfortunately the rear window defogger wiring / assembly is not very desirable based on my experience. I yanked a few complete assemblies and tried to sell them off and on but nobody bit. This has been 3-4 years now. So maybe things have changed. I was trying to sell the complete wiring for like $40.
The port holes you will sell. I think I sold my last set of glass and seals for like $40. The trim rings depend on color and condition. The last set I had were red and faded. I think I got $25 for the pair. Black is what everyone wants. If they are black and in good shape id say $40-$60.
The louvers are a good find. My cruising wagon had them at one time because I saw the holes in the hatch but I never found a set in the 8 years I owned it. Again it depends on condition. The nicer they are the more they are worth. I found a rough set a couple years after I sold my car. They needed refinishing and a little straightening and it was missing some of the prop rod things. I got like $175 for them. If they were in nicer shape I think I could have got $250 easy. I have seen one set go for $400. This was years ago though.
So if you make it back to the wrecking yard, as mentioned before the chin spoiler and brake ducts are worth grabbing. The side panels are hard to sell even if they were in good shape due the shipping cost. Grab the gauges, the sport steering wheel if it is in good shape. The sport door mirrors. The screw covers for the side panels are a nice find as well as they are usually missing. The rubber ones are by the front doors and the metal ones by the rear hatch. The AC jockey box thing that is near the shifter. Anything black interior that is good, dome light, visors, kick panels, arm rests, door panels, if they are in good shape they will all sell. The shifter boot if a 4spd and in good shape.
Again, this is all based on my experience. Good luck to you sir.
