Anyone use this type of hood pins on fiberglass

Got one in the center front, and one in the center both sides,. regular pins in the 4 corners and "back center, (edge of 6 pack scoop)." Wish I could run all push buttons, but don`t trust them that well.
A little tedious to get adjusted right too.

Forgot to say, Jegs has them for about $25 apiece----------
