Suntour XC Pro headset O-rings

[foxb13]

Hi,

I was dumb enough to lose the two O-rings on the upper and lower cups of a NIB 1" Suntour XC Pro headset. I bought it years ago, so don't even remember what happened to them. I think I can find replacement O-rings, but I need to know the inner and outer diameters. Can anybody help?

Thanks!
