Guys I have some GM numbers, first is on a Monojet: 7029017 176-9PD , next is GM dist 250 6cyl: 110293 3F5 thanks guys!
7029017= 1969 230/250 6 cyl.Date code could be the 179th day of 1969 if my memory is correct. Dist. number is probably 1110293 which was used from 1963-65. 3F5 decodes to June 5th 1963 if my memory is correct.
