is there an aftermarket seatbelt bracket available?
the one that is attached to the seat
preferably a set made of anything other than plastic
and also designed so it can be installed directly without having
to disassemble the belt itself in order to install it
seems like a simple design to make one custom

 

You mean the ones on the sides of the seats that the belts go through? I've got several greay condition stock ones that only require you to make one fine cut in them to install easily. Some are already cut. Whay color you looking for, and what year design? Get me you email for pics or other info, Henry

 

prefer something possibly aluminum but stock is cool ...pm sent
