Help with Exhaust Manifold Decode
I cracked the left side exhaust manifold while installing a new chambered exhaust system. I need to find a replacement with the correct casting/date code. The car was built the last few days of production in July, 1972. The exhaust manifolds on both sides of the engine are casting number 3932461. Below the casting number is RH5 and E31 is on the back side of the manifold.
What does the RH5 stand for?
What does E31 mean?
Thanks, Ed

Lyle: Thanks for the info.
The date code is on the back side of the manifold and not visible when installed. So to "look" correct I just need to find a manifold with the same casting number and any mold number??
