Also, possibly because there are so few original 68 big block A Bodies out there that few, if any, companies are going to be willing to spend the money to produce a part that may only result in a few hundred sales over several years. Bringing a decent quality reproduction part to market is expensive. Notice I said 'original 68 big block A Bodies' above. I focused 'original' because I assumed that most guys who stuff a big block into an engine compartment where a slant six used to live weren't going to worry about using a factory correct looking hose.
