I took the door glass to have it installed to a local glass company who gave me a good price. When I arrived with the glass and the frames with the old glass already removed, they agreed on the price of $20 for each piece. I talked with the installer and asked him to protect the pieces as this is an old car. The installer said "That is off of and old Mustang, isn't it?"
I left there impressed and felt assured that everything was OK. You could image how I felt the next day when I called and they said that he had broken one of the pieces. He broke the lower swivel pin off the driver side vent window.
Long story short, they offered me a $20 refund at their main office. I was asking them to pay for a replacement piece. While giving me the refund the lady said "You got a good price!" Then it hit me. The old saying of
"You will remember the poor quality long after the low price is forgotten."
I fixed it with Silver solder, flux and buffing. Tried to break it back off. That thing is not going anywhere. I will finish the glass install myself.
