It's in the '85 owners manual too, and I've been looking for a B2
with them for close to 20 years.
It's literally the holy grail of Bronco2 parts.
IT's probably the only option more rare than the rear bucket seats.

Not to mention the 4.0L and 8.8 equipped B2's of 1990.
Getting holes made isn't so much of a problem it's what issues will rise from it once done.
If those windows are so brittle that you tap them wrong and they shatter what kind of issues did Ford have? I believe this would be the reason for not going with it. Without super clean holes any bump or jaring and you'd have blown out glass. Not to mention I know how long it takes to get an engineering change through the system to update manuals. Hence the reason it was in the 84 and 85 manuals.
The idea is there but the glass is what would determine if it was a success or not. Ford did not have this figured out. The top curved part would have posed the most issues as clamping the window down would stress this area.
My thoughts would be that the first few that were in testing were having issues with blown out glass that they decided to just bond them in instead. Likely all the working prototypes were reworked this way. In 86 the windows were changed out for bolt in kind and different trim was used.
This is only speculation on my part, so take it for what it is.
It's likely easier to remove the windows and install polly w/canvas ones. It would make removal and stow alot easier. But this would come down to how well it was done. I have ideas, I just need to get to them.
