I noticed on the website for P. Winklers Vibrant, that the windows had been replaced. They appeared to use the original outside moulding. We recently bought Wind-Borne, a 1975 Ranger 33 that was a one owner and is in great condition. The windows however are really fogged and need replacement. I removed one of them and it appears that the entire unit, including the "glass" is moulded together. Can anyone help? Thanks.
