I am not sure if understood the question but the single cam injectors are top feed injector. you can not use then on the SR or the 91+ ka without a custom fuel rail.  
Also, you can not use ka rail on sr and vice versa without modifying the rail itself.

SR and KADE injectors are interchangeable, but KAE are not.

The side feed O-rings are all interchangeable… but do your self a favour and go spend $20 at nissan to pick up a fresh set.
