MacBook Pro 15" Airport card replacement

I have a Macbook Pro 15" Unibody 2.53 GHz Mid 2009 (one fan only) rather than a standard Macbook Pro 15" Unibody Mid 2009 (with two fans) and the wifi has stopped working - assume the Airport card has died. There is no guide to fix a Macbook Pro 15" Unibody 2.53 GHz Mid 2009.

I believe the card is located in the centre-back under the black clutch cover. I can probably find a guide to disassemble it eg the one for Macbook Pro 15" Unibody Mid 2009 to access the card and yes it may have some sort of model or identifier on the card once I get it out to be able to order one. But prefer not to disassemble it all before having the replacement part to swap out immediately.

I assume that Macbook Pro 15" Unibody 2.53 GHz Mid 2009 uses the same card as the Macbook Pro 15" Unibody Mid 2009 but does anyone know for sure or have experience with a Macbook Pro 15" Unibody 2.53 GHz Mid 2009 even including Airport card replacement and type?
