Thanks for that "wild guess" Pieter...you were right on the money. I thought this might be a little more difficult puzzle thatn most because of an artice I read in the latest special edition of Hot Rod magazine devoted to the Chrysler Hemi...there was a shot of the chassis from this car as it was being buiilt, and the car was described as being a much less-known effort on AK and Doug's behalf. The article also raised questions about the car actually being raced at the Mille Miglia. I knew about this photo from Chris Jones' book ROAD RACE , David McKay Company New York, 1977 that I found in a bargain bin in my local Kmart about 35 years ago.
Thought I might have a stumper...sounds like Hot Rod needs to do a little more homework.
