i saw your post on upgrading your ball joints to accept zerk fittings and thought you or somebody on the board might be intrested in our ball joint "upgrade" kits offered here at silverbullet. they consist of 90deg zerk fittings for ease of greasing, polyurethane boots to resist corosion from the sun, and a set of clamps to hold it all in place. we are under new management and are striving for better customer service and faster turn around time. thanks 928-344-2117
