Can't vouch for their outer quarter window fit since I haven't installed those yet. I have installed their door glass outers, and their quarter glass inners. They fit, and they worked .... but I'm no WS expert, I was just happy to get some.
If there are any areas of interest on the WS I can take photos of them since they are not installed yet.
