That almoust looks like an old Rockwell transfer case. I use to have one in my 68 and swapped it out for a 205.

You think that is odd...mine has an identity crisis...it says C4 on the bellhousing. (ford tranny designation for those of you NOT in the know)

RPO codes (regular production option) were sometimes cast into the bellhousing. My TH350 book doesn't list "7J" though. It says 69-72 models had a code stamped into the 1-2 accumulator cover or the vertical surface of the oil pan. For example, mine is Y9H20D, which decodes to: Y=Toledo plant, 9=1969, H=June, 20=20th day, D=day shift. The book also says the Vehicle ID number (VIN) is sometimes stamped into the passenger side of the case just above the oil pan flange near the converter.
