Wow !
Thanks for the responses !
So.. it sounds like the AD suburbans with "shiny" trim around the side back windows have had painted trim chromed.
I thought that the stainless trim on fenders and back door windows was only on panels.. and I think 1949 or so. Seems strange that this cosmetic option would be available on the 'utility' model
Thanks again everyone.
I will stop looking for that shiny trim !
