Is there an easy brake upgrade for a 1996, 3.7, FWD?

[woodshed]

The rattling of my front brake calipers is getting worse. It appears that the 3 pins that the cliper slides on are so worn that you can easily move the caliper by hand. Imagine how that sounds over the bumps?

I am struggling to get re-manufactured calipers. A few places list them but have no stock. I keep getting told they are like rocking horse ....!

Does anyone know of a good supplier or have a suggestion for a relatively easy upgrade?
