73 Exhaust Manifold #s

[David C.]

I replaced the headers/sidepipes on my 73 coupe with a stock exhaust system. The left rams horn manifold has the correct casting number 3932461. The right one has number 932461, (missing a digit?). Is this a completely different manifold, or could it have been a foundry error to leave off the first digit?

Definitely a foundry error.
