I'm not sure, Tim...My guess would be that JC sells them chrome because I'd guess most people would want chrome. I'm trying to establish whether or not it was a factory option or not...I'm only saying that I have not seen original equipment chrome mirror arms yet. That doesn't mean they didn't exist. All of the ones I've seen were painted something close to Pearl Beige. The other thing I wanted to ask is if anyone knows for certain whether the trim ring on 54-55.1 tail lights was ever anything other than painted black from the factory? Every NOS tail lamp I've seen, whether included in a turnsignal kit or not, has been completely black...No chrome or stainless trim ring ever. I think the 55-59's may have introduced these in their deluxe package, as my 56 GMC 100 has a very old, and decrepit looking chrome trim ring on its factory tail lamp. The right side lamp looks to have been knocked off somwhere along the way. Any ideas on the tail lamp conundrum?
