Replacing Perma Draw Carabiner Clear Creek

In clear creek canyon, what kind of carabiner would one buy to replace a perma draw carabiner with a massive groove?

depends on the route and traffic. almost certainly steel, and almost certainly one with a captive eye. something like this is ideal: https://fixehardware.com/index.php/fixe/climbing-hardware/carabiners/fixe-ps-clip-wiregate-carabiner.html

you can also alert the Boulder Climbing Community team of volunteers that helps replace bad hardware
