I have a complete 1990 jap-spec GT4 front bumper that i would be happy to sell. Came from the front-cut that i took mechanicals from. Not sure if it's the one your after however does have yellow foglights.
I have no idea what it's worth so you could just make me an offer. I am located in Darwin however i work for a freight company with head office in Ferryden Park so freight would be free.
