I have some 68-72 evaporator coils. I have cleaned them and pressure checked them with 175 lbs of nitrogen pressure. All threads are good on the fittings. Much less than a new replacement.

$100 plus shipping each.

I am looking for a working used original expansion valve to service and recolor for my W-30. I do not want new. (they look differant) If you have some used ones and don't know if they work... blow air through it in the direction the arrow points at room temperature. Then put it in a ziplock bag and toss it in the freezer. After it is frozen take it out and blow air through it again. If it blows less air then it is good. It is best to let it warm back up and do it again to be sure it did not stick.
