If you can get one of them out just take it to a machine shop and have a couple made out of steel. Shouldn't be all that expensive. When one of mine cracked I took the coach to a repair outfit that had already had a batch made up for Monaco coaches. The one that failed for me was under the refrigerator which is in the slide out. Slide makes a little more noise when extending/retracting but no worries about it breaking again.
It's also possible that Monaco used the same Power Gear rollers so you might want to check with
