Click on this link. You will see pictures of a Ford injector next to a Nippon-Denso injector used on a Mazda RX-7. As you see through its being modified to fit the RX-7 fuel rail. I found a set of these and so I'm out

The only reason I signed up on here was to see if I could track down this fuel injector.
Mazda rotary for ever!!!
The RX-7club knows about you........
