I had to replace mine and contacted Fountain last month and was told that West Marine was a distributor of Taco brand rub rails. They are available in 20' sections and the prices are very reasonable.

I bought a new one from Fountain several years ago when I couldn't get gas spillage out of the rail. Don't fill my boat anymore when winterizing.

I did not get measurements of my rail yet, to know what model number it is. It does appear to have been done before. Does this look like standard Fountain Factory to you guys?

I have a 91' 42 w trips' also. The rub rail on your boat was used from mid 90's to 05/06. I have the insert in stock & can get the rub rail within a week.
