Killer glass custom makes every piece. They don't have a make or model limit. You order and they make it, they don't make a whole lot of them a year maybe about a 1000 units a year (per their web page) turn around is about 6 weeks. As far as I know they are the only company that makes Pyrex coolant tubes. Just an fyi, they also make valve covers
I had a bunch of killer glass stuff on my silverado. Bad Ass. They will make whatever you want $$$$ though
