Rear control arm mount slightly bent w/ pics. Tips??
Hey guys. As I was installing my BMR subframe connectors, I ran into a problem. Drivers side installed perfect with no issues and everything lines up. I got to the pass side and when I slip the boxed rear control arm section of the subframe connector over my factory mount, the holes didn't line up. As I was looking at it, I noticed it has a slight bend in it. I know the subframe connector was designed around a straight car, and I would prefer to bend mine back so the BMR piece fits and lines up with no issues. Anyone have any tips on how to do this or what I should do?
Would really rather not hack up the subframe connector to fit a bent car.


In this pic, you can see that the part that the control arm slips into is bent away from the boxed piece of the chassis. The boxed part is what has the bend in it, so it needs to be straightened and tilted up slightly on the outside.

In this pic, the bolt is through both holes on the other side, and this is how far it's off. I really can't even twist it enough to get it close. This is the best it would get.

Well since I got no replies, I'm guessing either nobody knows what to do, or nobody cares enough to correct it. So heres my fix for someone who may be interested in the future...
Borrowed one of these babies from work. It's a porta power hydraulic ram kit. Applies 4 tons of force through a pump driven piston and has different attachments to fit it in all types of places. I rigged it up with the "L" attachments and put it between the control arm mount, and the part of the subframe just to the right of the control arm mount. Started pumping away and it had no problem bending it back where it's supposed to be. After some fine shaping with a hammer and prybar, it's basically perfectly straight now and my subframe connector lines up perfectly!!

Heres the finished shots...

Before, the control arm bolt would not just slip through both sides. You would get it in one hole, and have to "thread" it into the other side by turning it. Now it freely slips into both sides.
