2004 Sailfish 120 electric breaker panel replacement

Has anyone ever replace their electric panel on an 04 Grady. I have been searching for a replacement for the current panel and everything i find is a few inches larger. I'm trying to keep this to a fairly small project and would like to keep it where it currently is in the cabin. It is a pretty tight space and very little room for expansion and not much wiggle room with the wiring.. Figured I'd try the group before I called Grady. Thanks for any tips on OEM or manufacturer would be appreciated. Thanks
