Does anyone have this setup? I'm wondering about the geometry of the TV cable relative to the throttle linkage. One company wants to sell a $100 setup for getting it right. I'm not paying $100 for a bracket and a plate that bolts to the linkage. Holley on the otherhand just says you need this bracket and this stud. To the tune of about $20. That sounds more realistic. What have others done to get the shifts right?
