This weekends project, ideas welcome

This is a frame on one of my garden tractors that needs to be repaired. The frame is 3/16 thick, the crack is just infromt of where the power steering mounts. Ive read posts here on stopping cracks, fish plating ect. So what I thought Id do is fish plate the back, then weld up the crack in the front flapp it down so you cant tell from the out side it was welded. I only have my ranger to weld with, I know a mig would be better, still saving my pennies for one.

Any recomdations on rods to use or anything you all recomend would be helpful, TIA
