Not sure where to put this, but here goes (my cry of desperation)
I've just recently put my 1975 R16TS on the road again, and although it's in good working order, there's still a major portion of hard work remaining in order to get it into somekind of aesthetically appealing condition - interior and exterior both.
One issue that needs immediate attention though, is the lock for the front seat belt on the drivers side (left). The red plastic part (which you push to release the seat belt) has broken off at one end. From what I can tell, this red "thingy" is attached to a horizontal cylinder that in turn locks the seat bealt. When you press it, the cylinder is depressed and the seat belt released. Thus, I can not use that seat belt, which eventually will get me into trouble with the local police, should I decide to go for a drive. Any other suggestions are, of course, welcome as well.
Now, if I could disassemble that lock, I might be able to repair and re-position this broken part, but it has turned out to be impossible to the point of me believing the construction is not meant to be disassemled. At one side there are something similar to two insex screws, but from what I can tell, there's no means by which you can keep them from rotating at both ends while trying to unscrew them. Does anyone know if 1) it is at all possible to disassemble and reassemble these locks, and 2) if so, how?
