1969 Barracuda 340 Formula S Restoration

Assembly sequence woes!
I have the rear window mechanism’s installed some time ago but not the glass. Decided it was time to install the glass and get the catwiskers installed. Then discovered that the big black interior panel (in the last post) that I just installed had to come off so I could remove a body plug to install one of the screws that holds the glass to the mechanism!!
