Marantz 1200 platter stuck, collar came off with platter

[William C]

Platter got stuck on the shaft. Worked it off and the pressed on collar on the bottom of the shaft came off with the platter and was stuck in it. I got it out but bent it. It wont go on. Without this on the shaft the platter wobbles around and sits too low making it rub.
Anyone know a fix?

I looked and i cant find a shaft assembly online.
The part number is 4823100CEC
