SS Dana Axle?

When mentioning a plates between front spring hangers and body, to move the rear axle further back and use bigger tires, I come to think of the offset front spring hanger these cars had. Although moving rear axle in some of the divisions and classes maybe, this really is not what you want to do on a race car like this. To put more weight in front of the rear axle.
This maybe is, why Chrysler made this offset front spring hanger, so to say, a bit shorter than the OME hanger bracket. More than a quarter of an inch. Some 7mm whatever this is in inches.
Now, was this offset hanger bracket this way, to compensate for a reinforcement plate, (on the Hemi A-Body) like some of the Hemi B-Body had?
Or... did Chrysler make a smart move, to gain some Drag Race Car Technology advantages, by moving rear axle forward 7mm?
Pics below show a comparation between the hangers I´m talking about and a pic of a plate welded to the front spring hanger mount, of a B-Body Hemi. (Photo from Graveyard Carz)
So, if not front lower lip of the wheel well (of the Barracudas) had been cut, this plate, that some claim were used, has to be well over an inch thick.
Well, I believe it, when I see a picture of a ´68 SS/B Barracuda, with rear wheels way off center of wheel well.
I like picture better than words...
