Hi Michael,
As I said in a previous post, the body you show is an Australian workshop body of a 4x4. I have my photo taken at the auction, in front of me, taken from same side, tyres are the same, it has the same bend in the chassis, and the body is the same one, although as you spotted it does not have the cut out. Looking at rest of the body it is the same and I reckon someone had put in some filler pieces in the cutouts to hide the fact it was off a 4 wheeler, and they have since been removed. Even the lettering on the front is the same, no dispute, I see the radiator has been removed though.
Is it yours now?
regards, Richard
