Warning. That spring is compressed about a foot and there is a lot of energy there.
My car had a 1 1/2" spacer to help the spring which by now was not enough, I had to add about another 3/4" to it.
I got that. but in the thread there was a discussion of the hood not popping up when you pulled the lever inside the car. Mine has the same issue so I'm wondering how you resolved that - separate issue from the hood spring.
