Found my dads original 1971 duster!

Go over there and take pics of everything so we can see whats goin on. Your car came with a thermoquad. Not sure why an adapter is needed. Need to see what intake is on there. You could also have him take pics and send them to you. May be faster.
The car didn’t come with its original carb. The guy I bought it from didn’t have it anymore, apparently. I didn’t get a carb with the car. I can’t go take pics, as it’s being built 26 hours away. I’ll try to get him to send pics
