This picture is of the left rear interior side of my 83 CAB. Behind the speaker panel.
The bracket in the photo is pretty heavy with a nut welded inside for something.
Seatbelt retractor bolts on below and twards the front of this bracket.
The only thing I can think of is that maybe at one time during design they were thinking of putting a motor in to operate the top.
Another thought was I think Porsche offered a rollbar as an option or Tquiptment. Maybe this was a mounting point?
Anyone know what it's for?
