IR sensor does not work and I need to replace it. How?

Ok, so my IR sensor does not work and I need to replace it but can neither find the part here or instructions how. There is a description for the earlier MacBook Pro but not mine, the MacBook Pro 15" Unibody (Late 2008, Early 2009.) Help!

Yes, I have already checked the Security System Preference and made sure that it will accept IR, and that it is not paired with another remote.

Yes, I made sure the remote was working (I have 2 and used the iSight camera trick to see if it was working)

Yes, I checked System Profiler and made sure under USB that the Mac recognizes that it has an IR Receiver.

YES I have already reset the PRAM.

and YES I even ran a command line program called "iremoted" that listens for button-press events and prints the identifier (the HID element cookie, to be precise) of the button in question.

for example... (not my results)

$ ./iremoted

0x16 pressed

0x16 released

0x17 pressed

0x17 released

...

Since it is not recognizing any button presses, I'm assuming my IR Sensor is fried.

So, where does that leave me? Well, without a working IR Sensor and a need to replace it, but cannot find the part online or instructions how to do it.

So, any idea where I may find a replacement?
