Lionel parts number for headlight lens - Legacy K4, 6-84556

Does anyone know what or if there is a Lionel part number for the headlight lens on a Lionel Legacy K4, Mod # 6-84556?

I found the boiler front,  cs-6804556021-p, BOILER FRONT / K-4 #5493 for $42.00, but I only need the lens for the headlight.  I was trying to find a separate lens or headlight housing with lens that I could salvage the lens from.  I found some that might work, but it would only be a guess looking at the description.

Thanks, Dave
