Contact Jetworks, think he has one that he has made.
Could be Group K now that you mention it.
I’ll check the secret box tomorrowWant to add a girdle to a stock head. I think Pro Tec was the only company to make these but not sure, anyway if you've got a girdle that can be added to a stock head, I'm interested.
Think member Reg had gotten one of their motors last year and it had the half girdle kid. or was it Brapperdoodle???
