1968 a833 1-2 gear stuck

It was the interlock not in the correct position. I loosened the cover and got it positioned in neutral with a screwdriver. My shifter is also in need of some help. Several of the shims are missing which does not allow the spring clips to hold the shifter arms tight. I ordered some new ones from McMaster-Carr today. It shifts now, but will be a lot better with the new shims.
Thanks again everyone.
