I have a bunch of old quadrajets , but one stands out , it's finish is almost stock. It is number7032750 can anyone I.D.it?

 

Need more info. The # you want to look at, is on the driver's side of the main body going vertically.
Normally, it would read something like:
7032750 KG 2332

in this case, 2332 would mean made on the 233rd day of 1972.

 

Need to recheck that nunber, that number does not come up as a correct Qjet carb.
