    Default Oil cooler lines Leaking!

    I have a 88 GMC Sierra Classic ( R3500) (454) with the factory oil cooler and well its leaking. I have looked everywhere for these lines and can't find them anywhere. I went to have them fixed but they said the metal is so old that and they put new rubber hoses in but heres where its leaking from, right where the old aluminum meets the new fitting.. and well its very annoying and was wondering if anyone knows where to get the lines! Thanks!

    If you can't find them online then maybe they are a proprietary part, but you should be able to get them from your GM dealer
