timtam

Hey guys, Been working on my first timing belt replacement on my 1999 Subaru SRX Impreza, Its a manual with an EJ20 engine in it. It's been a great car and has now done just over 100,000 'ks (62000 miles) I finally got all the covers and other parts off and can now see the timing belt, But it dosen't look that worn so im not sure if it has already been changed or not: Here are some pictures: What do you guys think, do you think it needs to be changed? I cant see any cracking in the belt? if you need anymore info let me know! Thanks for the help!
