Yes, they welded the hinge (its actually 2 solid steel hinges. Don't know if that can be seen in the pics. They did weld it to the frame of the car and to the crash bar of the door. It is very. very sturdy and the actuator makes sure it latches prefectly as well. There is always a chance that there will be problems down the road but its like that with any car.... ie push button sliding van door, ect, ect. I did have a couple problems with the actuator opening the door within the first few weeks, but he fixed it, and seeing as it's a "one off" job and probably the only Camry in the U>S. with an auto suicide door, I didnt have any problems with the early on issues. He also warrantied all the work and parts for a year. Nothing lasts forever, and if it gets messed up, Ill get it fixed... I have had it for 1.5 years now and use it daily many times a day, So far so good. I live in Gainesville Fl, which is about 45 mins from the GA. Border. It was hard to find a shop to do it, I did find another custom shop in Gainesville that would do it but they wanted more money than I wanted to spend. I think I got a good deal. You are much more likely to find a shop in So. Fla. Like Miami, Ft, lauderdale ect. The guy who did the work is Named Rob Martello and here is a link to his facebook page. https://www.facebook.com/rob.martello?fref=ts He is a nice guy, but he is also very busy.... he may or may not answer any tech questions you have. The name of his shop is Addicted Performance and Sound.
