Posting for si Banker who's not of the computer generation. We spoke on the phone and he told me a little about these decklid hinges. They're CNC machined out of a single billet. You can drill them if you like. He's getting back to me regarding weight. Significantly less expensive than the other offering and I'm only guessing lighter and stronger. Finish looks great!
Things to note: I have not seen these in person. I have no connection to the maker. Pm him for purchase/questions/arguments/compliments.
He's also making other parts: optima battery holder, seat slider cup holder, and front hinges. I'll post another thread on those.
