Exhaust manifolds
Picked up these manifolds at a swap meet last weekend. I'm curious as to what year truck the would have come on. My 77 manifolds don't have the cast ribs between the ports and I've not seen any others like that. Every thing else on them are the same as my old rusted ones. I'm thinking I can eliminate the casting ribs without hurting the integrity of the castings? The casting date one the one that is legible is D 21 8 or 6. Help in identifying these please?
