Where can I find this rub rail?

I am restoring a boat built in 1983 and would like to replace the rub rail but I have no clue where to find one. It is a simple piece that wraps around the seams evenly,held in by rivets. Also,is this a preformed piece or will I be able to make the curves around the bow with a straight piece of rubber? thanks.
(I posted this in two categories because I wasn't sure where to put it.I will delete the inappropriate thread.)

 

There are many types and materials used. Yours looks to be extruded PVC, though I can't tell if it has an insert.

It's just a simple molded piece.It looks like this "c"
I didn't see one like mine at taco

 

Call them up and see if your boat is something they have a die for. It's an uncommon boat and not likely listed on their profile guide, but they might know of something that is suitable.
