They are nice, but a pain to install..you will be cutting through the top skin, and the substructure, but the cut on the underside has to be bigger than the top to allow you access to the holes that the bolts go through. And it all has to be done perfectly to match up to the pin location.I also ordered a nice set of locking AeroCatch pins for my new hood, I managed to score a nice 4" cowl hood for cheap. I also found a coupe trunk lid, so that saves me a ton of bodywork on the current one.
Not for the faint of heart.
