This has been the typical shape for the BB upper hose #3979192 on the 2nd gen cars. (As well as small block - showing different number -->3970124) all the resto houses sell this shape - I believe it is wrong. After researching a while - I think I have an exact match on what it is REALLY supposed to be. Here is one I made (top), next to the original hose I found. What do you guys think? - Is this correct? I am still looking for an original BB lower - any one have one?
