So I “borrowed” the one from my Alfetta Sedan, still need one to replace the borrowed one. The old cracked mirror was missing the spring clip, so maybe that’s why it was mounted in that manner. Here’s a couple of pics, NOS and the offending mirror.
I'm just wondering if all the metal brackets are the same, as previously mentioned, I boorowed one from another car, I can't find a part number for the one used in the Montreal in the parts catalog even though it shows the image, there is no part number associated with it. It seems just about everything else on the car has a 105.64 prefix, the part I am using has part number 188.8.131.527.01 from a 1750 GTV but used on later models and others I suspect, reached out to John in the Netherlands to see if he can help. TIA
