If you have an early set-up, you probably have the little secondary bellcrank mounted on the intake. You can eliminate that and just use the bigger bellcrank thats on the firewall. You'll need the adjustable link that goes directly from the firewall bellcrank to the carb. That's what came on the later models. Check with Toms. They should have one. I like carb linkages more than the cable type. It's just smoother.
