In your second pic, i see the casting number for the case, and the strip of little squares is the date code. In your third and fourth pix, there is the casting number and the date code for the oil pump housing. I cant quite make out the PK number in the last pic
Trans was built on Wednesday, January 17th, 1968
I believe your PK part number is 2892031; A727B 1968 Dart, Belvedere, Coronet, Barracuda, Fury, Charger, Monaco, Polara, and Newport w/ 383-4bbl.
@69Coronetrt are you able to help?
