'96 GT - Need size for Bleeder Valve / Screw

Hey All! So I hope it's cool if I temporarily hijack the SN95 forum as I SHOULD be in the foxbody area ('88 GT) but I've converted my front brakes to '96 GT's/5-lug. ;)

Super great brakes, btw! Unfortunately the bleeder valves on my calipers are rusted so bad that after a rear brake rebuild, I tried to bleed those fronts and they were stripping.

Upon searching and product hunting, I keep coming across two different sizes depending on 'who I ask' online, and I wondering if I could get a definitive answer here.

I'm seeing either:
3/8"-24 X 1-1/4" or 10MM X 1.0 Thread 33MM Long

Which one is the correct one?

Thanks!
