My '83 has 'em. They all work too. If yours are shot you might try a conversion van shop for replacements. They're still putting those things in vans. Mine give my cabin that definite late '70's early '80's retro look. I'm 99% sure they were there since new. Most of my boat has not been touched. About the only thing that appears to be unoriginal on mine is the swim platform and the dark blue paint on the outside. If you got pics, send me some. My email is
