727 one bad clutch plate. Input to output washer half gone

Us tranny folks refer to those "not flat" steels as "heat warped"..

So it got real hot.
Another thing I found

That clutch pack has a very flat wavy retainer clip, and not a flat selectable one.
The trans date is July of 1970.
Unless someone shaped it before me, that is not right for the year
