Need ball joints for Burgard A-arms

[bigb426ex]

For the past two weeks my brother has been trying to get ahold of Burgard but too no avail.... Does anyone know if there are other ball joints that would be the same for a replacement that he uses? He didn't see any part numbers on the ball joint. They were for the upper ball joint for a stand travel + 1 a-arms on a LTZ-400. We were hoping to get them before a race this weekend.
Thanks in advance,

As long as you have the cheaper arms he sells, which most do, go to advance auto (usually cheaper) and get 69 VW tie rod ends, they are the same.
