As you can see in the picture the driver side of the bumper is a little low. What would be the best method in evening out?

 

There is a small amount of adjustment you can get from looening the bolts and moving it around. Your bumper looks bent from here.

 

I was going to say the same thing. The bumper on that side doesn't look a little low, it looks a lot low, and I doubt any amount of adjustment could make that much of a gap go away. The bumper, a mounting bracket, or something is bent out of shape.

 

Which bolts should I consider looening? I'm a visual learner, so any pictures would be great.

 

There are 2 bolts on each side that mount the whole assy to the frame. There are a bunch of carriage bolts that mount the bumper to the bracket assys.

 

An 800 ton press will fix that,... maybe.

 

That bumper looks a little bent. I have the same issue on the passenger side of my 72 Vista. Only thing you can do really is to get it professionally straightened out.

Are you sure there are no bends in that bumper?! If so, no bolt play is going to fix that. Look at the picture I have attached. That one little ding in the front of the bumper puts that side out of alignment. I think you might have a similar situation.

 

I agree someone heavy used it as a step and tweaked it, find that guy and put him under the bumper and lower car on him to straighten it back out.

 

If it is a real nice driver and not looking to be a high end show car you can straighten them on the car. You can adjust the bumper but if it is bent then I have used jacks with blocks of wood, blankets and big rubber hammers. I have got them very straight this way. Just go slow and easy. It is also possible you can just loosen the driver side frame/bracket bolts and just push up on that side and tighten it up. If you have some mechanical experience you can likely get most of it out.
