honks I found that the metal is as thin as. I pulled out the frame and welded it up. Very thin, weld grind, weld grind, weld grind...The crack is from the panel flexing when the wipers are on. Check the wiper pole and stick some lube on it . Mine was a bit rusted and seized.
You may be able to cut some alloy plate and drill a hole the size of the pole and stick it on with sika flex. A piece right across the front might look ok
