I just recently placed a rebuilt rochester QJet listed for the 72 camino 350 V8. The throttle lever was twice the size of the QJet #704 2210 0812 QE that was previously on the engine. I found out it was from a 1972 pickup. Well in trying to change the detent cable so it would fit the new carb the snap lock (plastic) clips cracked off so it now has nothing to hold the cable in place and rests useless on the engine. I been driving the car with no sign of change with cable unattached. How important is a functional detent cable? The parts guy said I would have to find replacement snap-lock in junkyard.Is this true? Can I switch throttle levers on carb and make a custom fix to hold cable in place? Sorry, for the long post. Thanks, Jason.
