I called the body shop again today.
I got a different person, who is now the General Manager. He revealed to me that the entire administrative staff of this place quit on the same day, didn't leave much if any documentation, made a lot of promises in both writing and verbally, and didn't do a lot of the things they agreed to do for customers. He told me that he'd research it and get back to me. He called me back about 10 minutes later and told me that they didn't order the windshield like they'd told me on the 8th, and he will take care of it.
I decided to stop by the shop today after work, and had a good talk with the new GM, who was more than happy to put everything into writing, showed me the truck, and assured me that he will get the glass purchased and will have it installed the same day it arrives.
So, I requested another quote from the Japanese supplier, this time with their shipping address, and he'll buy it as soon as we get the quote back. He said he doesn't care what it costs, because that's the price and he needs to get it taken care of. So... It's getting shipped via air.
The truck looks great, except for the lack of windshield glass. Lol.
