Morning folks! Hey, I could not find anything other than universal power motors for my RoadMaster till I finally asked my retired Master Tech GM buddy. Now this was for a 92 RoadMaster but I imagine they have others that might help some folks out so just sharing it so you don’t have to go through mountains of advertising for “plug & pray” universal stuff. Hope it helps: https://www.theantennasource.com/BUICK/ROADMASTER/RoadmasterSedan1992-1996.html
