set fire to the bush and it drops out (blow torch, or metal container containing oil, diesel, petrol, thinners, anything that burns for ages, always works for me), then there should be a 2mm (if that) thick ring left in the hole, hacksaw through it, chap it out with hammer and chisel, insert new polybush, job jobbed. i used powerflex bushes in mine. http://www.ebay.co.uk/itm/Powerflex-Poly-Toyota-Starlet-Glanza-Turbo-EP82-EP91-Rear-Beam-Mount-Bush-/380663925776?hash=item58a1568c10
