737 J rails for IPECO J rail seats. Virtually impossible to find, and extremely expensive if you luck out and find a set.  This is 1/2 of a full set; complete for the F/O side.  Using these as a pattern you can have the left side duplicated.  In the end you will save a LOT of money, time and effort.  Made from composite material, stronger than typical plastic.  However; while fine for home sim use, these will not hold up under daily abuse in a professional sim.  We have sold 30 sets which have been used successfully in home sim installations.
