Good luck, I just got some for my 62 k20 form a guy on here. I placed a add in the wanted area. But I did just want the painted ones.
In all my looking I never saw a crome/ stainless one. I looked on other sites too. Dare I say I looked at old Dodge and the F word ones. Most of those mirrors were made by outside suppliers. So look on other makes.
Yes jr west coast are the mirrors on the c hoop. The rectangle one that used the same are as the round one was just know as the optional mirrior. But all the sales lit i have calls waht ur looking for a Jr West Coast or camper mirror.
What ever it is call doesnt matter. Good lucking in finding what you want.
