z5 mount stud thread size

[Greg5OH]

I lost the nuts holding the cross memebr to the trans mount. (right on the trans).
Any one know the thread size and pitch? I believe its M12x1.5?

im pretty sure thats right.
my standard optical gauge is on spot. metric... not so much
1/2" corse? lol

i believe its metric, takes a 16 mm socket perfect, from what I recall. Could have been cause they were old and had crud built up.
if its std, that owuld be 1/2"x1.5?

im dumb, i should put a tap on it and then ill be sure lol

while ive had my 87 torn apart sveral times, ive found that some of these bolts are actually standard.
i just went and looked at mine, im using 1/2" corse thread (standard)
there are only 2 pitch sizes for standard. corse and fine.
i trid to dig out my thread pitch gauge. but i made the mistake of showing my son how to use this tool, and now its not in its spot...
bout to ring a neck!
