Help identifying 12 bolt!

[Wizit247]

So from any of my searches my stamp on my 12 bolt doesnt have as many numbers as it should. can someone more knowledgeable than me decode this? or point me in the right direction.

This is stamped on the passenger axle tube just like it should be. There was only one number cast into the center section. it was tho lower right if seen from the rear. cant remember the number. it started with a G and ended with 55.



Much appreciated!
