Having the right tool is best, but the secondary rod hanger fits that double D perfectly. Also the Q-jets I have seen on the late 80's Chevy trucks had an enrichment solenoid that looks just like the CCC solenoid. It had no CCC but used a temperature sender to operate it. Not knowing the part number I would have guessed it was a 1980 Q-jet. That year was the first for the electric choke and had no solenoids.
Didn't know about that tip but sounds like it would only work for making a preliminary adjustment with the carb off the engine. I doubt the hanger would fit while performing a running engine adjustment.
