he's right, the back small window is crowned and not reproduced, take what you can get
I just checked with 4 different parts suppliers, all 4 had listings for the small window glass, most even had 3 options, Clear, Green tint, and Smoke tint.
If you're planning to work this truck and drive it regularly, you might consider intalling
this style back window. I have one in mine, and am very glad I did it. Especially in the summer.
