Which size have you gotten for what and how did it fit? Anyone bought one for a '67 or 8 and it was almost too tight? They seem to be listed with the "up to X"" for a size, like up to 157" and such or if they are vehicle specific then they don't tell what size they are. Seems like the last generic one i bought was a small and it was still too big. I want to get a nice one that i won't mind being snug.
