BMR Relocation brackets/LCA install?

I am in the process of installing BMR relocation brackets and Lower Control arms on my 08 GT. I have the FRPP 1 inch drop springs on it right now. Its up on the jack stands right now and the brackets have been installed to what should be the correct position. The LCAs do no line up with any of the holes in the brackets. I have wiggled hit with a mallet and honestly I have run out of ideas. Anyone know what I could do to make the fit?

Make sure the rear axle is at ride height. How far off are the holes?

Yes the LCAs are facing the right way. How do I find the ride height? I thought the using the jack stands on the axle it would be a ride height? They are off by about half a hole.

When I installed LCA's on my old V6 I just put a jack under the gear housing on the axle and jacked it up until it lined up.

I wish I would have used a hydraulic jack under the diff as suggested above.
Yeah jack stands will have it at ride heigth. I called BMR and asked for some suggestions and they said put the wheel brake on and try to man handle the tire to try and rotate the axle enough to move it into position to line up and then have a buddy put the bolt in. That didn't work out too well for me. I wound up laying on my back and putting my foot on the tire and my shoulder snugged into a wall pushing the crap out of it to move into position and we did it that way. You can put a beefy screw driver in the bracket hole you want to use and then through the lca hole and test movement. See how much resistance via lever action just to get an idea of what you're working with. That is the hard way, I would use the jack on the diff. Don't use the bottom hole on the brackets either, that's overkill. I would use the highest hole.

I will give that a try today. This has proven to be much more difficult than I had originally planned. I was thinking the top hole myself

What I beleive is happening here is that the angle of the rear axle needs to rotate up a bit. You might try removing the panhard and read sway bars to get the axle to move more freely.

or try this... use the jacks stands on the frame of the car, then jack up the read axle with a floor jack.. right now the wiegh of the car is being transferrred to the rear axle, so its not so likley to move.

One thing a friend of mine had to do was he put a jack under the connection between the pinion flange and the driveshaft and jacked it slightly. That rotated the axle a bit and lined up the holes.

What's your opinions on the brackets? What are you feeling with the car now?

I really wish I would have had them on before. the wheel hop is reduced to nothing now and I assume that when the car is accelerating the geometry has been changed in away that helped smooth out the shifts a little more. The car seems to really respond and not squat in the rear I hated that before.

What about when you are turning? Notice any difference?

I had similar issues, here's what's up.
First of all its easy for the rear axle to start to move forwards or backwards without the control arms. I ended up using a comealong (i think its called that) to pull it back to position.
The second problem I had is that BMR didn't make the brackets right. They were far too narrow for their own control arms to fit into (yes I did have them facing the right way). They had to be seriously FORCED into the brackets.
