Looking for aftermarket mirrors like on the 66-77 bronco to go on 88 bronco
 

I want to get rid of the stock mirrors on my 88 Bronco and want something similar to whats on the 66-77 broncos, but it seems they only had one for the driver side. From what I understand a truck has to have two mirrors so I was wondering if somebody knows where there is mirrors that are similar to these but come as a set.
