Hey guys I had a hard time finding the correct seal head for my 1991's rear shock rebuild so I wanted to pass along the info to help out anyone attempting to do this job. The third one I ordered was the correct one, turns out it's the same one as a 1991 CR250R.

The correct dimensions for the seal head is 14mm x 44mm

I used a Moose Racing one, part number 1314-0046
