I am not sure what you run on the track, but I would wait on the boxes.
My friend (mufflerboy) runs 12.8 on slicks and we thought for sure that his boxes would be gone. We put it up on the lift to weld them and they were perfect!
Now! He DOES have subfram connectors and aftermarket arms.
If you have the rear-end out, and do not mind taking out the interior sure go for it
