Need Advice Installing New Toilet Flange

[Rhyder]

I need to replace wax ring and flange on old toilet.

When I took the old one off, the pipe broke on top as it is now uneven. The old flange get had 2 weird metal nail spikes securing it to the ground and of course alot of the concrete is chipped away so how does a new flange get secured.



Attached a pic so you can look

Looks like the flange was high to begin with, looks like you could cut the pipe flush withe the floor and home depot or Lowe's makes a pvc repair flange that you push inside the pipe
There is a rubber ring you thread up or down, and then you tighten the flange by turning it clockwise,use a concrete drill bit and (tap con) concrete screws to secure the flange to the floor,there are other methods but if your not handy this is best
