If you're installing headers, for ease of installation, you'll want the powertrain as close to the stock location as possible.
Unfortunately, it's really hard to tell what's afoul with your single picture.
Maybe you could post some pictures of your engine and trans mounts.
Someone may see something obvious to them.
Also, shoot a picture of your frame ball bracket. Maybe it's been relocated at some point?
In any event, try to get the bell crank "straight across in any view".
BTW, this may be an "optical conclusion" by me, is the engine perpendicular to the firewall. Your picture appears it's canted toward the passenger side.........
