I haven't been able to find any data on the known crash locations of any of the bombers lost. I have found a website that list's most of the bombers included in the raid, and looking on the Wikipedia articles goes some way towards making the list look genuine (as the squadrons listed did take part in the raid, according to wikipedia).
However, to find more information on the lost bombers the website I've linked to may provide you with some pointers. For example, the list linked to lead me to a veterans group website for the 98th Bombardment Group. The page linked to lists the bombers included in the raid and many are listed as "Shot Down in the Target Area" such as the Margie (the aircraft name)
42-41007-P; MARGIE
P CLARENCE W. GOODEN (KIA)
CP Jerome Savaria(POW-ROM, WIA)
N Ralph F. Parkins Jr. (KIA)
B William H. McNeil (KIA)
T Michael J. Trick (POW-ROM,WIA)
R Theodore C. Beaudry (KIA)
G George H. Kaylor (KIA)
G Harry G. Deem (KIA)
G Alexander M. Cockrane (KIA)
G Roland B. Cox (KIA)
Shot down in the target area.
My recommendation would be to see if any newspapers in the area talk about the finding any wreckage, or if any museums about the city in the war/about the raid (if they exist) can help you to narrow it down further.
