Well dont forget an eight of an inch of steel isnt an eighth of an inch of armour, The steel has to be treated before it gets the armour label. I think rolling for instance makes the steel denser as well as more 'even' or homogenous.
Also, besides the windows the other characteristic that makes this vehicle unique amongst all other armoured vehicles is the completely unprotected underbelly. Theres an awfully exposed, big fat fuel tank and lines under there.
And of course edges can be joined, turned, beaded etc, you really need to take in your hand drill, drill a hole through the middle of one of the panels and measure it there, just to be sure.
Best Regards Chuck.
