Hi 69GCBC, Those parts are easy to find,

details"
items 15 and 16 are PMA approved replacements for orginal Scott
parts, the Aircraft Spruce #'s are Tinken Bearing #'s. If purchased from local supplier (bearing supply, auto parts, etc) they may not be approved aircraft parts, and may not be available if you specify that they are for aircraft use. As an additional note the same bearing is used as the pivot bearing in the bottom of the fork. Have fun, Tim
