Am I being blind again? Where are the nipples on the front calipers?

Should have paid more attention when I changed the brake pads a long time ago and had plenty of room to work.

It took a bit of running around but I was able to find the 9mm for the rear. Of course I thought I had a 9mm until the car was jacked up and the rear wheel was off.

I got the rear brakes bled although I wasted a bunch of fluid bleeding the first caliper. It continued to look fairly blue going through the tube I was using. I should have been looking at the fluid & not the tube. Luckily I had extra fluid on hand.
