Looks nice,but it's really for a 1970 SS Chevelle,because it doesn't have a Thermac mounted snorkle pot & heat stove like the '71/'72 SS Chevelle used.

It's also a later over the counter GM replacement,as it has the later issued over the counter two bend PCV vent tube design too,and not the smoother transistion tube as was used on the assembly line.
FYI~Both vent tube designs will fit all carbs. & are not carburetor specific.
