1997 V8 stock shocks

Would like to confirm nut specs front and rear shocks. Haven’t removed them as yet so can’t check.

Did some research but I’m not certain on the thread pitch. Some people have had grief.

Conclusions so far are:

Front , both top and bottom are M12 x 1.25 class 8.8 nyloc.

Rear, top is M12 x 1.5 class 8.8 nyloc. Some sources say this is a flange nut ?

Rear, bottom is M12 x 1.25 class 8.8 nyloc.

Is this correct? Thanks for the help.
