I have a red top optima in my car, but i don't remember what number it is. I didn't have a height problem either - i did have to run the lower installation tray that came with it. I'll check when i get home tonight and post what number it is. There is a picture in my photo album.

edit - take that back, the system will not allow me to upload the pictures of the engine bay with the red top.
