If you have the latter engine with the nylon insert and small green o-ring, you are welcome to buy these injectors, but we do not carry those seals. The nylon sleeves are NLA, and the small green o-rings are still available as of May 2024. See our listing for Late 1974 and 1975 4.5 injectors in the related products below
