Hey Dave, couldn't find the info you're looking for, but found this page which includes a couple book references:
353rd FS History - Part One
Refs:
History in the Sky - 354th Pioneer Mustang Fighter Group; 354th FG Association, Editor: Capt. Arthur F. Brown.
Air Force Combat Units of World War II - The Concise Official Military Record; Department of the U.S. Air Force; Edited by Maurer Maurer.
Modelers' Society Journal - Special Limited Edition: The 354th Fighter Group In World War Two; Doug Gifford, Jim Pierce and Walt Fink; IPMS/USA.
It sounds as if you've exhausted the internet. Time to hit the tried-and-true library (it is, afterall, all that was available at the time this information would have been recorded).
