Hy Mr Goodwrench, I think the hose you're looking for is GM 3883151, that one doesn't cross into the Napa line, my other thought would be to use the Napa UP6100 with a Weatherhead adapter 7917 on each end, check that stuff out at your local Napa and see if that will do the job for you. I checked all my brake hose illustrations and could not find one with 5/16" inverted flare female on each end, I hope the fix I mentioned will do the trick, if not let us know.
