major clue there
69 azz end .......69 case ... 68 side cover or shifter forks n hardware from the original tranny
the partial vin will /should be .. within a couple inches of the date stamp
smaller than the date stamp .. and closer to the mid plate ////
on top facing the floor of the car ... right against the bell housing...
I have seen some early ones vin stamped on the machined surface the side cover bolts to
ON THE case .... there a little pad that hangs out next to the gasket...where the date is on this one..
so with the 69 tail shaft and lever that makes it a little tough t o get the back up
lite switch to work.....68 only style,,,,
