The only decent way to straighten it without cracking it is by heating the aluminum. The bad part is the location of this damage to the gas tank.

If you can shield the gas tank from the heat, use a propane torch to heat the bent area of the lug. To see if the temperature is hot enough to bend, scribble on a part of the lug with a permanent marker. Make sure that you don't apply the flame to this part. When the marker looks like it has disappeared, it is hot enough.

Put a big pair of channel locks on it and bend it back straight. Try not to pound it back with a hammer.

Like the idea of marker as i hate heatn alu as raeely works out well

I have hight heat resistant tape from furnace that shoul help

It really isn't that hard to take off the rear subframe. Since you crashed hard enough to bend the lug, you may as well see if you broke the subframe anywhere.

Looks like previous owner damage as the exhaust pretty beaten up. May still look take it off. Cut lug off and get welder in work Tig back on
