It's probably tough to make a call form the pics but derailleur cage is angled inward at the bottom toward the tire. This is an older STX 8 speed, and it's riding rough through the outer sprockets. I'm thinking the derailleur should be perfectly vertical, and this hangar is bent. Contemplating the the best way to bend it back out. Wanted to get a few affirmations before I started bending though. Also, any ingenious methods for straightening would be appreciated as well.

Thanks
