Well, does anyone know why an April built 70 428 scj would have the exhaust spacer on the Rh manifold? The 428 registry indicates that this stopped in December 69. The manifolds are original to the car(pretty sure anyway). Fuller exhaust is on the horizon and don’t want to have any fitment issues. Am I missing something?

Likely the manifold has a much earlier casting date. What is it?

I can barely make out any casting numbers. I had to resort to to old crayon rub method to get anything due to pitting. Would it have been possible for this manifold to have been installed in April 70 even though the 428 registry indicates December 69 was the change over to without the spacer?
More likely the manifolds were installed on the car and the date is incorrect for production. The 1970 Cougar needs 1970 exhaust manifolds to be correct. These are right for an earlier car.
