I have followed VFH "instructions" but I make the thing with the paper clip a bit short, it dont have to go all the way up when you push it, just past some "marks" that the cup holder has... I think that in the 1st pic they can be looked.
Cup holder closed - making pressure with my finger as if it were the spring, the lid remains flat.
there are 2 arrows... the left one shows like a flat surface behind the rounded part (where the paper clip goes), the other shows like a fixed gear where a circle spring can go in
that shows like a "L" where the other end of the spring can go in
I'm just pressuming... I will chek this weekend with one spring I have that is supposed to be from the car...
