Big block k frame and oil pan

Is this an actual Dodge manufactured Big Block A Body K Frame? Or a torched, cut, welded, and grinded, A Body K Frame- set up for Schumacher Motor Mounts?
Don't get me wrong- Both are good, in fact both are excellent. Only a few of them are the real deal Mopar Component.
Pardon me if that sounds like I'm coming on to strong, don't mean to sound like an a hole, it's just that I already own one of above items.
I'm more concerned about owning the real deal.
Thank You,
