Dana 60 brake bleeder question

[jms]

CUCV Dana 60 front, brake caliper bleeder screws; mine are tight to the point that I'd rather have a replacement at hand when it's time to bleed the brakes. So:

NAPA sez the bleeder screw (1984 K30) thread is M10 1.25
Autozone sez the bleeder screw (1984 K30) thread is M10 1.50
O'Reilly sez the bleeder screw (1984 K30) thread is M10 1.50; Dorman # 13908 or 12702
Advance Auto Parts comes up with the same two Dorman numbers; so does Rockauto

Who's right?

Could be any size from 7/16 to 10 MM. Older trucks, which have had a lot of work done on them, could have any number of given size bleeder screw, if the calipers have been traded in for a rebuilt set several times over at the part store.

Get a thread pitch gauge, and you will be able to figure it out yourself. It is part of the fun of owning an older truck.

I'll say NAPA is wrong. They are horribly inaccurate at listing brake parts, among other things.
