I have a old relay outta my '72 here, it's fairly fresh just setting on the garage shelf for years now....I THINK i'ts a GM part from way back.....now it's got black paint on it, and last I checked, it worked well.....I will look it over and test it to be sure if you interested....
but not sending jack until I pretty sure it's a go....
lemme know....PM is best....
