heres what ive found based on the reference books i have at home: center section casting numbers are vague for early 70's nova but 1235542B was used in 73 and 74 camaros so your center section number is right in there. your other numbers are difficult to decipher as they should be in the form of a seven or eight digit code and you have a total of ten and dont describe where they came from and or located. the only other info that may be valid is the QJ code as that particular code was for a 3.07 posi from a 67 camaro. maybe some more info on location and in what order would be helpful kurt
