Help finding replacement part

[Steco]

I need to replace one of the two channels into which the transom seat cushion slides but A) Don't have part # B) Not sure of proper part name C) Can't find it anywhere. Can anyone point me in the right direction? Attaching pic.

Get yourself a piece of UHMW polyurethane on amazon and make one with a table saw. Easy stuff to work with.  W
