I am putting a Titan Mk5 back together. I need a drawing or part for the radiator and oil tank. Also, is there an approved way to check the upper frame rails for soundness seeing as how they carried coolant for years? They have some scale, but I'm not sure if they're bad or just ugly. Thanks for any help. BTW, I'm in southeast Michigan if anybody has a Mk5 or 6 I could visit.
