I have the shelby hoodpins, I mounted brackets onto the radiator bracket that extend toward the front of the vehicle maybe 2 inches. Had to cut wholes in the plastic radiator cover as well for the brackets, then put the pins in, and greased the tip of them, shut the hood and that was my point to start.
I had to drill into a cross brace for the hood so I was drilling at a 45 degree angle to the hood to start off with...disgusted me.
then hearing my brand new hood, grinding and chipping away...I almost puked.
But all in all it turned out well.
There are four screws holding the billet plate to the hood, since the hood was slightly curved, if I used all the screws (same length) it would dent the hood, so I had to go to a local hardware store and get half inch longer screws for the rear two holes of each plate, just to reduce the denting.
I am pleased with them so far, the left pin which was tight before now slides through the whole loosely, so I will have to adjust that...which is a pain.
Good Luck!!
