Yep, did it to my car just recently. It's really not that hard. I had the front end off mine and it was on jack stands that were placed on the frame under the floor just back from the firewall. Make sure the car is level before you start. Get a piece of paper and a pen. Take measurements from all angles eg., cross corner , side to side , from the front of the old inners to the firewall etc. and mark them down for reference later. I even put a mark on the ceiling of my garage and took measurements from that to the inners as well and from the inners to the floor too. This is so when you put the new inners in you can check to see if everything is lining up as before. Then go ahead and start drilling out the spot welds. I recommend one side at a time and after the new one is welded in move to the other side. This way you won't have to brace up anything. I did not brace mine when I changed them. This may sound confusing but it is not that difficult. Just take lots of measurements to go by and check them as you proceed. Mine all lined up perfect and everything fit back together nicely. There will be some grinding and clean up of the welds, no big deal just take your time. I did one side one day and the other the next day. Gives you lots of time to look everything over as you go. You can do this, trust me.
