just take the old one out and put the new one in, just make sure your intonation is correct.
Measure from the nut to the 12th fret and then double that. That measurement is your scale length and how far away the bridge saddles should be away from the nut.

To put up a pic. Get a photobucket account, upload pics into it. Copy and past the IMG code.
Good Luck!
