Default Futaba S3004

I know this is a stupid question, but beginners are allowed, right? I understand the purpose of the rubber pieces when mounting the servo, but if I follow the Futaba manual and use the pieces they provide (brass grommets and rubber insulators that appear to mount on the top of the servo) it doesn't seem that the rubber will insulate the servo bracket against the wood plane. Does it do the job, are the pieces incorrect, am I dreaming?

Help!!

From Futaba's website...


--------------------------------------------------------------------------------
Proper Servo Mounting:
The proper way to mount a servo is as follows:

Insert a rubber grommet into each of the four servo holes.
Insert a metal eyelet from the bottom side of the rubber grommet. This way the wide portion of the eyelet will be in contact with the servo tray when mounted.
Test fit the servo in the tray, and enlarge the openings so the servo will not touch the tray. The rubber grommets will isolate the servo from the hard vibration of the airplane's structure.
Position the servo, then mark the location of the mounting holes. Drill pilot holes with a 1/16" bit at each mark.
Use the servo screws supplied with your radio to mount the servo(s) in the servo tray. Tighten the screws until they just touch the top of the metal eyelet.

Default servo insulation

On the Futaba S3003 and S3004 series, the grommets are not the
individual pieces that the older ones used. These are supplied in
a strip of rubber that goes across the two holes of one side of the
servo. The brass eyelets are also a little longer than standard.
What you do is use a strip grommet on each side of each servo
flange and insert the brass eyelets from the bottom. You are then
sandwiching the servo flange between the two servo grommets.
Check out the pic below where I pulled apart the grommets on
one side of the servo just enough to show what I mean. You
should have been supplied with enough grommets, (4 per servo),
to do it this way.
