The 1984 and earlier trucks are a totally different design, than the 1986-1993 Mazda trucks......that is why the link you posted for a 1986 B2000 won't work for GoldenLemons truck. Everything about those gas tanks are different than the 1984 model that he is looking for. No need to feel ashamed......nobody knows everything! But we are learning! Thank you for trying to help.....that's what we're all here for, in my opinion.
