Don't know of one but honestly have not purchased one in years. At that time all the replacements IMHO were too wide and the ends stuck out a little more than I liked.
And yes - as mentioned_ much lighter.
Just found out last week that my local yard dumped/scrapped all their original bumpers (couple of hundred) got tired of them
Wished I had know before hand - purchased a dozen or so over the last year (dated and pretty straight - no real rust out here) for $20-30 ea
But them again I don't know if I wanted to get into the rechromed original bumper biz either
