But it's a 69-71 carb. Not aftermarket, it's over the counter. No different than me going to Dodge store and buying a diff gear set today for my 17 Ram.
Now if he wants a correct date code for 69, that's different.
If it's a 69 car with a 71 carburetor? If the date code reads like Murray was talkin about. Also the SA suffix like HemiSSDart said. The SA is aftermarket, like the old Carter Competition carburetors.
