I need some help with an old Dodge truck.

Also, I think the Dodge Canadian 230 is 25” and the US 230 is 22”. The guys on the Pilothouse Forum would know, and one of the would probably have the manifolds you need.
23” and 25”. My 218 is 23”
There is a guy , on facebook selling parts. I will see if i can get you a linky.
