My mother and father's house was built in 1974 and an ITE EQ40MBB 200 amp breaker box was installed. Over the years the bus bar behind the breakers has pitted from arcing and such and I have relocated breakers in the box until I am about at the end of my rope. I am looking for just the guts to change out due to the box being encased in their brick wall (bad mistake on pops part). I have talked to all my suppliers and Siemens and nobody can come up with the guts I need. I have measurements on the hole pattern I need the guts to be: 7" across from side to side and 29" from top to bottom, but I can't find any like that.

Any of you know where I might look next or am I going to have to start sawing brick. I hate to do that as the house is a very good looker and you will never match brick that old.

BTW how do I post a pic of my schematic???
