Drill them POS torx bolts out and put in some new bolts/nuts.. It's tough, but you can get a wrench up in the dash without removing it. The driver side is a little tighter since you have the ebrake and whatnot, so if you pull out your speedo/tach cluster you can access it a little better. With changing to normal bolts/nuts, it's a lot easier for future work in case you need to remove the windshield or whatever. Hope this helps.
Edit: Your main concern is going to be the driver side because the pass side will become 98% useless once it's moved up and forward..
