Can anyone give me information on where to find a replacement track for my plexiglas entrance door of my 1991 33' aft cabin (35' wide body aft model) The model # is 3307. The door rides on a top and bottom tract with small wheels att. to a slide that fits into the tract. The track is black and 58" long and prox. 1 1/4" OD wide. I have tried to order through my local Carver dealer and keep getting the wrong part. I have been told the track changed on the 1994 350 35'aft model.
