Inspection of a 904 torqueflite

The annulus support I broke. The part replacement came in today.
The part from 67 and 76 has the same part number.
The teeth in the 76 are taller.

There is a sub number
67 L28
76 L23

I thought I would post pictures of this NOS replacement box. It’s date coded 76 and the teeth measure correctly. I would say I got lucky with this as finding a loose 4/4 gear of only the one part I broke would have been kinda rare. They switched to the 5” gear not too long after this I think and 76 was the first year for the 4/4.
The 5” came out not much later and they retired the 4/4

Cool old box I’ll save

I don’t know why it posted the picture twice
