I am talking of the hood pop-up spring that attaches to its base on top of the grille for a 69 Roadrunner. On the last coil it has a small section of spring jutting out at right angle from the coil, and this fits in a raised tab with a punched hole; opposite to that a portion of the last coil must slip between the base of the grille and under a small retaining tab. I think that trying to compress the last coil is very hard to do if you slide it in without damaging the paint in the base
