Cat 943 rear belly plate

My Cat 943 doesn't have rear belly plate and the underside hoses and track motors are in danger. I need a new plate or get one made. Does anyone have a picture or schematics drawing that I can use as a pattern please. Nobody seems to able to even find a part number for the belly plates - not even Caterpillar!

I've seen the fittings for the plate under the machine, I just need a plate or the dimensions. I can't measure it as I'm about 800 miles from the machine. It's in the bush and I'm at home in Perth, Australia.

Thanks,

AG
