LMC has them for $13.

Remember the master needs to be bench bleed. I just did my 64 after doing all the slaves first. I should have done the master first since the increased pressure caused the master to blow fluid all over the interior and brake fluid is not nice to painted surfaces.

I know it's not OEM but I added a set of “speed bleeders” front and rear.
My goodness, what a way to turn a bleed job into a pleasurable experience.
