Hemi Chrome Dome Air-Cleaner Base with Large Carb Openings (5 1/8")

Hello- I'm looking for a '66-'69 Hemi Chrome Dome air cleaner base with large (5 1/8") carb cutouts. There's a seller on eBay that seems to be unresponsive these days. Is Classic Haulage in Ontario still around? Any ideas where to find one?

Thank you!

Bob
