RX-7 injector conenctors

[Neejay]

If I can get some 91 RX-7 injectors, what do I do about the rounded connectors?

What's the simplest thing to do about these injectors?

if you plan on using these on a sohc ka rail you need some injectors out of a 80's fc. All you have to do is take a dremel to grind a small plastic tab off the inside of the plug.

I dont know if a 91 is a fc or not but my rx7 injectors are out of a 86 rx7.

These are all listing for a SOHC

I personally use the 91 Top feed injectors on my SOHC and I just had to use the dremel tool a bit took me a whole 45 mins for all four of them.

Yeah, its a 91 NA FC. So I can just use a dremel and they'll be fine?

Bah...I was under the impression that they were plug and play. That's where I was confused.
