Decoded the fender tag

The 6 under AX is for an open 3.55 8.75. No small bolt pattern Dana's. No non-Sure-Grip Dana's for that matter (in cars anyway). If it were a Sure-Grip rear, there would be an 8 after the 6.

Not beeing sarcastic: I also know there´s no sbp Dana´s. That said, what about the possibilities that: there´s misprint from the factory, or me filling in the wrong numbers?
