A nice 1956 Oldsmobile 2 door hardtop right rear quarter window regulator in good condition. Regulator moves freely now - adding grease would make it even better. Regulator has 26 teeth and the arm measures 12-1/4" spring to roller center-to-center. Plastic roller is froze up and should be replaced. Spring is broken and a replacement part is available. All teeth are good, and so are splines for window crank.  Four mounting threads are good.

I removed this regulator from said vehicle years ago thinking it would interchange with a Chevy - but later found out it does not. My interchange says it fits 1956 Buick Special and Century hardtop and late 1955 Buick 2 door hardtop. Also interchanges with late 1955 Oldsmobile hardtop. I am not a Olds/Buick guy so please verify your application.
