I'm trying to find out who makes the air controlled throttle stop cylinder on my race car, it has "Hardcore racing product" decal on it but I haven't found anything on line that looks like this one. I need to buy the ball stud fitting that goes on the carb. linkage for this to hook to, I hope the picture works well enough for someone who knows the company that makes this and the contact information on them to help me find out who to buy the parts for it from
