I'm going to remove my old radiator suppotr bar and replace with a new one. I going to grind out the old spot welds to remove the old one. But do I have to weld back the new one? I really don't know how to weld and really can't afford to take to a shop to do. Any help help would be greatly apprciated.

 

First off, why are you removing it?

 

I had a front end collision.

 

Post some pics, sometimes it's better to try and fix it than to split the factory welds. Also, chances are, not to be a downer, that if you damaged the rad support to the point where it needs replacing, the complete front end may be out of square.
Best thing would be to leave it on until you find out whether or not your fron tend is swayed over or not, it's easier to straighten out with main structural components still attached.

 

It's swayed just an 8th on an intch to the left. I'll post pic's soon.
