    I was tightening the a/c belt when this nut fell on the ground from between alternator and engine .Its a 17mm nut with m10? thread same as bolts used for the cv joints.I am not missing any cv joint nuts and they have a taller tapered section than the spare nut.I have looked all over the engine and cant see anywhere that it could have come from.

    I think it secures the alternator case (bottom left as you are looking at the alternator from the wheel well). I think this is the bolt that the alternator pivots on.

    It may also secure the alternator to the sliding bracket.

    On my 78 GTS, I can see a nut like this when I check out the parts diagram #31

    I know it’s different size but it looks like the nut for the CV joint

    You are right Mike its the same size and thread as the cv joint nuts just slightly different in appearance , that was my 1st thought as well

    I was hesitant to click on the post due to the title. I was relieved to see it was a mechanical fastener ;)
