What’s up Scott, I have done plenty of those. What they are looking for is that if the car ever was in an accident, it is fixed properly so that it's road worthy. Another words, you wouldn't kill your self nor you wouldn't kill anyone else. Make sure every single nuts and bolts are in place. The second and this is the case in most rebuilds; they need to see where all the parts came from. They want to make sure that you are not using any stolen parts. So if you fix the car the properly with documented parts with receipts and all you will be fine.
Now this is where most people get stuck. You have to have a rebuilder’s license to do this. I always go through a buddy of mine and give him few hundred bux or so. He always takes care of it for me. I don't know if the law has changed now but that's the way it was few years back. If you are serious, I can talk to him and see what he would charge. Also if the car is over certain years old and a rebuilder sends the title in without getting the car inspected, they will still issue a rebuild title. I believe that our cars are old enough where they don’t need to be inspected.
