Rear Bleeder Screw Size

I had to replace a blown brake line this week and went to bleed the rear drums, and the bleeder screws are mangled. Wondering if anyone knows the sizes off hand. Parts stores have a lot of different ones, but if I ask what size I need, they just shrug their shoulders.

If the cylinders are still OEM, they should be M10 -1.5 X 30 mm.

But if possible it would be best to pull one and bring it in with you. Often it is the case that reman wheel cylinders have had the bleed bores drilled out and re-tapped one size up.

I ended up having to get new wheel cyls because the old one's were rust welded. The new ones I got both have different size bleeders even though they are the same manufacturer.
