its a trailblazer 251 G However, it is open on the back. I have measued one of my friend's machines and he just put a stainless cover on his but his frame measurements are the same as my machine. So Im looking for a new blue skeleton that doesnot leave my machine engine fully open as it does now. If I could get one in stainless that would be ok but I really want a new cover. The frame demensions are: Width(18") X length(45 1/2") same as the bobcat 225 NT. If you can help I would apreciate it.
