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 7/8 ths of a full set, missing 1 section from the captain's side. You will have 7 of the 8 genuine sections missing only the captain's section with the stop holes. Using the right side as a pattern you can have the missing piece duplicated. In the end you will save a LOT of money, time and effort. The photos include pictures of a typical 737 installation, as well as ours for sale.
