Meh, Jerry turns out some cool stuff. But every now and then he has a goofy hiccup and he will go out of his way to make sure you know it's your fault. After reaming stud holes on countless regular heads, re soldering the vents on several Billit bowls, and the catastrophe over my one piece head. Sure hope he gets things fine tuned if he wants to keep moving Billit. I'm just to the point where I'd rather spend the extra dinero to not have to fiddle fuck with parts.
I think if I ordered one more part from chariot and had that happened, I'd just send it back and ask for money back. Packard is the originator of these, I bet he's got what you need NOW.
