You are talking 60k miles,that's about 100k km's, mine has 3 times as much, think that's a clear hint to change them!!
I hope I find a reasonable rebuilder here in Spain, last time I asked for a timing belt kit they asked 110 $ for it,(original VW, but even then!rimmed belt 38 euros!!) when I look at American websites I get absolutely jalous about the availability and prices for parts you guys get.
