Hey Zach, it only says B16 on the info sheet that is in the closet door, not sure what the difference is between the B16 or B17, maybe just a few options?
Seems like there is lots of bigfoots for sure! Ive found a few people on instagram that have built 1980's ones, popular item right now!
Lots of work to be done though. Thought only the back window glazing had to be replaced which is hard to find, but now The one seal for the back driver side window is leaking decent. Sent a email to sunview windows
so hopefully i can get an answer soon!
