I have a bike with older hayes brakes. I have been trying to bleed three rear for a month now and can’t get the right fittings. I purchased the hayes pro bleed kit and nothing fits the port on the actual caliper. The fitting that came off is in the middle of the second pic and the fittings that came with the kit are on either side.
It looks like I can just loosen this fitting I took off and fill it that way, but I don’t have anything to connect to it. Does anyone have any tips or advice for what to look for? I keep ordering things and starting the process, but then stall due to missing parts.

The caliper fitting stays in the caliper. Loosen it 1/4 turn and put your tubing over the nipple and use that to push fluid into the caliper and through the system. The official instructions have a squeeze bottle, but a large syringe should work as well.

The New Hayes Pro Bleed Kit comes in 2 flavours… Legacy and Dominion. The Dominion kit is for the Dominion series (A2/A4/T4) Legacy for their older models.
Judging by the pair of fittings, which are identical to the kit in my toolbox for my A4’s… hate being the bearer of bad news Hoss, you have the Dominion kit.
You mentioned having a few of the amazon bleed kits, they should, big should in quotes here, have a fitting that will thread into your lever.
That caliper port stays in the caliper as mentioned by the other poster, however. Much akin to a Shimano Deore or SLX. Its a Press on Hose kinda deal, followed by a quarter turn to open, push fluid to lever til the bubblies stop bubblin’ in your top syringe.
