So the car I have been restoring had a custom aluminum evap tank that was fabricated to replace the original one. I have not been able to cross reference as to whether or not the original is to be of a plastic kind or a metal kind. I am curious to know if the later model 71-73 or 72-73 (whichever it is), can work on the early 01-70's. I believe the hoses I have are actually the OE hoses and look to be in OK condition, but as far as I can tell- those are also discontinued, along with the clamps on either ends of the hoses too, right?
