Hi Dominator8811, that is a bad bend in a bad place, you are going to need an arbor press or the equivelent, and make up some supporting fixtures to press it back. In short, you'll neet to support/suspend it from both ends horizontally, and make a U shapped yoke to straddle the frame, and press on a cross piece at the area of the bend? It will be tricky as the frame may not want to bend where you plan, so some adjustment and flexibility in the fixture will be required? Constant measuring as you progress will be important as well, so you'll need to make some type of, "GO" "NO-GO" gauge as well...
Most of the time, 99% of the time, they are bent the other way?
I think yours is bent in the easiest way in order to repair... Good luck, best, til.....lat'r....GT
