Welcome to the site !!
As far as I know everything "should" be the same with maybe the exception of the valving itself ....they did change in 10 , like going to 48mm forks , but prior years (04-09) "should" interchange with no issues as far as length , etc. , mainly the valving would be the difference , and you can always remove the valving from yours (the Fork Cap Assembly) as a unit and swap it out .......
If your Rebound rod is leaking , you can simply replace the seal ( not simply , but I can walk you thru the procedure if you have decent mechanical skills its not that hard and a 17mm Allen socket that is 1/2" drive and a breaker bar and a propane torch and a drill , I walk people thru the procedure all the time) , same goes if the inner cartridge seal/Free Piston seal is leaking , you can replace that as well , so if that is a option for you (depending on what is exactly wrong with yours) , just ask and I will be glad to guide you thru the procedure ....
