Need some info if possible please
 

Hello everyone, I am new here and I'm hoping someone could give me some information. I
WAs recently helping my parents and came across a complete set of 4 1988 35th anniversary white center caps in great condition. To my knowledge the white ones were custom as most were chrome in color.. But any info at all is greatly appreciated.. Thank you
