I did on my '87. �Bought from one of our vendors. �Replacement was fairly easy since they need to come out when working on window removal, as I was. �There's a one-piece top run and the bottom is two separate pieces; one inner and one outer. �Roll window down. �Yank the top one first by prying it forward at the bottom-back of the window opening where it meets the bottom pieces and then peel it out. �Bottom pieces can be pried up and out. �
Reinstalling the bottom pieces can be tricky since you need to fit the pieces into the little stamped clip edges that hold them. �Easier and cleaner than exhaust work. �Good luck!
