I can't find a Plastic Man story (at 15 pages it would have to be for Police, not Plastic Man) in Woolfolk's style in the appropriate timeframe, let alone one that fits what may be "crazy crimes."
"Blackhawk against Blackhawk" is in Woolfolk's style and published in a month you might expect. The villain's name in the published piece is Mung; his plot involves midget radios.
I could find the title of the Wild Bill Pecos story, as changed from Woolfolk's, but not its page count; his previous lead stories for The Westerner have been cut by a page or so. The Wanted story may have been published under another title.
Publishers: Quality, Orbit, and Fawcett.
