My commando valve covers on my '67 cuda are just like that...breather tube on the driver's side and a pcv (with a grommet) on the passenger's side.
I often wondered if this was correct as most of the other commando valve covers I've seen and two sets which I've purchased do, indeed, have the breather tubes on both covers. :dontknow:
I think commando valve covers also have different wiring straps (can't think of a better word other than strap) on the passenger side covers depending on the year.
Perhaps others will chime in and clarify the differences.
