General question, (and Gene) this is the stainless weld-on adaptor from Vintage Air, I am not sure what kind of weld or braze to use as the OEM steel lines seem more steel then aluminium alloy so rather then risk it, would it be possible to drill and tap the stainless adaptor (if there is enough material) and use a pipe short nipple ? Living near a small town in the country has it advantages, ... this is not one of them.
