Driver seat is off track

Unfortunately once the seat track is broken the only way to repair it is to replace it.

People who cant weld will say re place the lot ,but if there is crack or a break get someone who is not of the throw it away type ,and get someone who can weld it up , if i lived in America i would picking up your sealed for life units and frames like yours and make a fortune out of repairing them and selling them, what a wonderful throw away world we live in !
