Studs in back of door

[Rollright@aol.com]

Yeh, 
 
That's you, lurking out there.
 
Seriously, the "lift the dot" stud on the top of the rear flank just  behind 
the door, that attaches to both the tonneau and the soft top, is  anchored on 
the bottom with sheet metal threads.
 
I want to change it for better anchoring to a BOLT  style.
 
How the heck to you gain access to the underneath of the stud to get a nut  
and washer on it?
 
?????????????????????
