Thank you will probably just fix with fiberglass.Is your left-hand hood panel completely missing or beyond repair by a good body shop? Is this a fiberglass panel or metal? (Since it's a DX, probably fiberglass) Yes, it's extremely expensive, but it's also a specialty part, and New Holland probably only sells one or two a year if that many. You are essentially paying for the part and paying rent on shelf space in the NH warehouse.
EDIT: These tractors are out of production, so parts are not being built in production quantities.
