Cracked the control arm bolt

[Ncie Gyu]

Yesterday i was changing my front, left, lower, forward control arm. It went OK until i was going to disconnect the ball joint from the spindle, it took a while and had to modify some tools, but eventually we got it to get lose but not enough to actually pull it out beacuse the shocker wasnt giving it enough space. Thought i might have to remove the lower back control arm to ease on the tension. But as my 18mm boxend wrench got stuck trying to remove the nut from the ball joint, it freaking broke the bolt as it was getting harder and harder to screw it back in. So now this was taking me longer than i excepted to get it fixed and i had to get out of the garage i was using. So i just kinda let the rear control arm sit there and then i tried to get everything back together without even changing the forward control arm.

I got it scheduled to a mechanic next week cus i dont see myself coming up with a solution to this, but is there a way to fix the bolt to the rear control arm? Or am i going to have to buy a new front, left, lower, rear control arm also?...

My english car lingo is not the good so in case nobody understood what i meant this is where i broke the bolt off: http://imgur.com/a/H4TGQ

You will have to replace the lower rear control arm. the threaded portion that broke off is part of the ball joint.

Allright :/ thanks

edit: can anyone tell me the OE number for the control arm i broke? I'm getting crazy trying to find the right one cus every website list their assemblypositions differntly "lower, back, front, left" , "left, front, back, lower"
