Justin – be aware early wheel cylinders had a “double” bleed nipple with a small (M6 with a 10mm a/f head, I think) blanking screw inside the larger diameter bleed screw.

If you still have the old type, to bleed them the small inner screw needs to be replaced with a bleed nipple to accept the bleed pipe and then the large screw, which is the actual bleed device is slackened and tightened as per modern one piece nipples.  As long as the big screw is tight you can remove and replace the smaller one without any risk of fluid loss – or air ingress.

If the wheel cylinders have been replaced there is a strong likelihood they will have standard, one piece nipple so no problem.
