Shorty arm with roll bar

[TheTexasTornado]

My RC10 has the shorty arms but no roll bar in the front, are the roll bars hard to come by and whats the best way to put the ball end in the arm for the mini turnbucke that mounts to the sway bar from the a arm

The kits are on ebay a fair amount, and they come with a 2/56 threaded ballstud for the arm, and the 4/40 threaded rod and ballcups and all hardware for the kit ( which can also be used in the rear )
