Swinger 1969
Because of large wheel tubes and I wanted to use original read deck lid I needed make some support system.
Rear deck lid weighs about 43 lbs (20kg). The original support system was out of question.
I decided to use one or two gas spring to support the rear deck lid.
(Gas spring is 16.5 inches long, 6.3 inch strike and has 450N )
Here is some pictures. (At the moment I need only one spring on RH side of car.)
