273 Commando Valve Covers and air cleaner

You could use a black lid from a slant six car and have it chromed! I have one (the bigger cover) from a slant six I got on ebay, it is identical except it is not chrome, The base plate I can get anywhere, I will just buy a generic one for the base. I believe the original Commando base plate only fits AFB carbs, too small for an AVS or Holley.
