2008 Mobile Suites 38 RL3 fireplace

[firemedicd]

I need to replace my fireplace and can not find a brand name, model number etc on the old one. I can not find anything online that matches the dimensions of the old one. It was in a fitted space with decorative wood work around it that I would like to save. The dimensions of the old fireplace with the trim included is 23 3/4 w 22 1/2 h 8 1/2 d. Any suggestions???
