<VV> Vented or not...

[Secular]

  Hi:

  Could an unvented gas cap (on my 1960 Monza) be converted to vented without
  purchasing a new one?

  If so, could a small orifice drilled in the cap, accomplish this? 

  I'm not particularly cheap, but a vented gas cap for a 1960 is rare!
  Is there a gas cap from another vehicle that fits the '60? 

  I tried calling Stant to inquire about their instant-fill:

  But, the folks at their customer service are clueless :)
