Does anyone know how to get rear bottom cushion out of a 2000 mustang gt I have to replace abs sensor,it doesn't seem to come out like they used to by pushing rearward at the bottom.

There is two push like clips/buttons between the seat bottom,and chassis where the bottom clips too.Just put your finger between the two,they are roughly at the quarter points of the seat bottom.Push,and lift one side at a time.
