I can put a rebuild kit together for any q-jet with or without a number.
That carb is a poor choice to replace the original 1976 Pontiac q-jet. NOTHING is right about it aside from the straight in fuel inlet.
Linkage is wrong, wrong type of choke, incorrect vacuum source in the rear of the baseplate, and "goofy" linkage for the throttle cable. It also lacks the large front vent to locate the air cleaner base and seal off the leak there......Cliff
