Hey all

I'm in the middle of servicing my 2012 SID XX 29er forks. The replacement seals I got came with a foam ring, however there was no foam ring in there when i pulled them apart. Have Rock Shox changed the design, or have I got the wrong seal kit? (Kit definitely says for SID)

Also, when I pulled them apart, I found what looks like a 10mm spacer on the negative chamber side of the air piston. My forks were supposed to be 100mm - but I always thought they were about 10mm less than usual - according to the markings on the stanchions. Could it be that they came set at 90mm? My friends forks were the same, so I just assumed the markings were wrong.
