so special about those that required CNC machining. To me it looks like you could get tubing the same size as the stock A-arm press some bushings that will accomadate the stock bolts. Then take a hefty grade 8 bolt of about 3/4" to 1" weld it to the two end pieces and then get a coupler to join them. The way I see it the only measuring is the width and diameter of the end pieces. I am not trying to be a dick, but what's so special about them?
