Hello. I'm not saying that is the best way to do it, I'm saying that is how I did it, because everything was already out of the car. There are many ways to do it, though... Some say to weld them in with everything in the car, sitting on it's own weight...But I don't know, only time will tell if I did it right...I hope everything lines up and the doors shut with a nice "click" once I put it all back together. lol...OR I could have possibly twisted the car, and welded them in wrong. LOL...Only time will tell...I'm pretty sure all is good though. :)
