Since those are junk anyway you might try something I read about years ago. If the issue is that they seem too "narrow". Somebody wrote that you could lay a towel down on a surface like a work bench, put the bezel on it upside down, take another towel and using both hands push the edges down which would force the bezel edges to become wider. I bet those things can flex out 3/32 on each side, maybe a bit more due to spring back.
I am wondering if during the chrome step if the machine that polishes or buffs them puts too much pressure on the sides or perhaps they are shrinking after being molded. See if you can make them fit.
I had 5 NOS in the envelope deluxe bezels that were raw pot metal that I had all chromed with the rest of my stuff and 2 of them as warned by my buddy at the chrome place said pocked up big time and half dissolved. I did get enough for my wagon and 1 spare. You have nothing to lose by trying.
