Luckily for me I never messed with the later TQs with all the emission stuff. I was out of professionally working on cars by 81 when they started putting computers in them. I always preferred 73 down stuff and personally was stuck in the mid sixties to 1972.
Me and you both! I consider them parts carburetors. The trucks though, used good Thermoquads all the way to the end of the Thermoquad run, as long as it was not a California emission vehicle. The cars didn't get so lucky. LOL
