Lower alt bolt size!!!!

[Xargon321]

i have a 74 260z and the lower alternator bolt came loose while i was driving and took leave of my car so i need to know what size is it so i can get a replacement!!!!.

If it is like a 240z, which I suspect that it is, it takes an M8 X 1.25 bolt. The bracket has a blind hole 32mm deep, so somthing in the 40 - 45 mm length range should work.

no the one on the bottom the long one that the alt pivots by.

I am almost positive that on my 72 240Z there are 2 bolts at the bottom (where the alt pivots). The hole DOES NOT go all the way through the Alternator mounting bracket. You use 2 bolts, one from the front and another from the rear to secure the Alt to the bracket. I don't remember the length of the bolts, but 8mm X 1.25 is correct.
