Hey guys… so after googling it I see its a common mistake to strip the shaft of the clutch, I thought I was the only idiot!

Anyways what is my best option just die the end of the shaft and continue on? I think i need a new piece on the inside of the primarty clutch with the teeth on it as well.

Now i also notices some play in the shaft of primary clutch, its moves up and down and left and right but barely any play at all. Should i just replace the shaft? or is that play normal? thanks guys appreciate it.!
