67-9 camaro rear end housing #'s

[GS STAGE 1]

Do these numbers tell you this is a 67-9 camaro rear end housing........3969340NF, this is all the info I can get out of the owner, he's not up to wire brushing the housing for the 7 digit code on the axle tube
Any help appreciated

If you go to camaros.net do a search of that number, you'll find a few threads that talk about it. seems to be a very late 69 or more likely 70 or later 10 bolt.
