I bout these connectors and I am wondering where the two square shaped brackets are welded to. I haven't gotten the car up in the air to get the welding started. Also does that weld through primer really work, is it recomended? I'm also maybe thinking of powder coating them but you have to gind off a lot of the coating. I know that the're connectors that come coated. Has anyone used them? Any help would be great. Pics of the type that I have installed would be even better. Thanks!
