Seems like the wheel base would be different from my reading this car has a 133.5 wheelbase did the 633 sedan come with a 133.5 or just roadster? Also attach frame and motor numbers match..
Or any other parts for it for that mater? Pretty sure it’s a 1929 runabout. Seems to be they changed to the single body line cowl sides rivited onto 1929 000703 cowl.
