apologies, i just re-read my post and realized it's somewhat vague. the windows to which i was referring are the windows in the doors that roll up and down. in the model #43 (and, i believe, the other Riviera models as well) they have a stainless trim around the glass. on the #41 the door glass does not have this stainless trim.
is the door glass on the Rivera just the sedan door glass with the stainless trim around it? i.e., will adding the trim to a #41 window make it work on a #43?
i hope that clarifies it a bit.
