Dacor downdraft vent

remodeling kitchen
can I change top piece from white to stainless steel? We just recently replaced our 30" white Dacor cooktop for a stainless steel. The countertop downdraft ventilation lid is in black, located behind the cooktop and would like to purchase one in stainless steel to match the new cooktop. Our downdraft is in good working order and do not wish to replace the entire mechanism at this time. Please inform us if there is a replacement lid. It does not rise, only flips back to open.
We have taken the old lid to metal fabricators and they cannot duplicate it. Please advise......Pauline
