Why do 72 frames look tweaked in the back?

My frame looks like the back is a little twisted and I have noticed the same thing on a lot of other frames also. Is this my imagination or is it due to the tracking arm being on an angle? I'm paranoid now that when I boxed the frame that I welded it tweaked. Anyone know how to measure it and be sure?

It's the member that sits at an angle and is normal.

Re: Why do 72 frames look tweaked in the back?

So are u saying that if I set the bare frame on my shop floor (which is a known flat surface) and measure it from the ground that the frame rails will be exactly the same distance from floor or should be?

Maybe I'm misunderstanding your question. This is what I'm refering to as being angled. The middle brace.

measure across from a identical point on each rail to the end of other rail. Like an X. This measurement should be identical.

Yes you are exactly right that's what I am referring to. Hmm too bad I don't have one of those.. The reason I'm worried is because I cut the rear frame horns off of Attempt/Mistake #2 and want to check it all before I paint it and find out its all screwed up
