Carried on welding the dash, need to make defrost vents but not in the mood. Very nearly went home as getting cold again, cant afford to run space heater and electric blower cost me extra on electric bill . Decided to mark up roof infill as first one distorted, noddled it and decided to refit and clamp to see how it lined up. Looked good so managed to spot weld the one side, tack welded the front edge and no distortion . Got my mojo back!! will make inner strengtheners between header and frame tomorrow that should hold it in alignment.
