fork seal

Hi folks. Am now getting into a rebuild on my 1976 cb500t. I gave up on it in 2007 when I acquired a Beemer, and it got a bit neglected. Anyway, the rebuild is now well underway, I have been relacing the rims today which I had blasted and painted and am now looking at the rest of the front...

I have been pretty conscientious in taking photos during my dis-assembly process but failed to take photos or make note of the orientation of the fork seals when I removed them. I am at the point of installing my new ones and need help with which way they go in. One side has a larger groove...
