yep, should have said adapter, i was thinking one thing (adapter) but said another (jack).
feel like a fool now as I see the blue adapter pops right off the main part of the jack (surprized the heck out of me when it did), and the date code 9E I have is on the gray part of the jack. There is a UN in larger font after 1969 stamp on the adpater, and all this is under the camaro stamp. VE3 is on the back of the adapter. I dont think any of this info on the adapter can be date coded to a particular car build date now. sorry for wasting peoples time.
