yes that is right they are the first ones you see in there, there is a thread somewhere.
But I can tell you it is very simple you just need -
1) some tape (I used the fabric re-enforced stuff)
2) a pair of tweezers (if you are thick fingered like me)
3) a small flat blade screwdriver,
you apply tape to bottom of plates onto throttle body so to catch the screws if you drop one it cant go into motor, using the screwdriver in one hand have tweezer ready once screw is almost out, once all are removed and all screws are accounted for remove tape and plates. ... job done
