Keizer you can buy the retrofit kit and shelves for your 6030 from Amsec or have an Amsec dealer order it.
When I was looking at these safes the only model the dealer had was like yours in the fact they had no Stor-it shelves.
I noticed right away after they installed my BF last Friday the backing which is covered in carpet is made of thin sheet metal as you can rap on it and tell.
I believe it is like that to contain and fasten the metal shelves.
The backing on the non shelf units seem a bit stronger and are made from some sort of wood i do believe.
The extra $58.00 my dealer charged me for them was well worth it too me.
