My parts book only go up to 1967, I have two relays and not sure of the application. I have a 75 Cosworth, 77 Monza V-8. I tried searching it on the internet and they are listed for everything that the seller can use to sell it $$$$$$
They look so familiar......
Group #4.075 part number 3961573 (7 digits????)
Group #8.778 part number 403651
Thanks

The number group 8.778 #403651 fits 68-72 Oldsmobile rear defroster relay. I find a lot of odd parts that I have with GM numbers on them. A lot of the time you can find them at GM WIKI by just typing in GM and the part number. Not all will be found but most. That's how I found what this fits. Chuick
