welcome to the forum its a great place to get your questions answered. Pull one of your furnace vent covers and measure the floor thickness that is what I would do because the differences in these rigs.

Thanks for the welcome and reply but mine doesn't have floor vents. That is what I did on my last one I had to repair. I will probably just go ahead and cut out the section then get a measurement and run and get the piece I need. Just thought I would ask first
