Try ringing Noletec at Thornleigh, Sydney. If you give them your lower control arms at they will cast in some urethane bushes for $250.00.
They did my 1986.5 and they actually had some arms is stock, so I was able to swap arms and give them $250, same day.
By the way. If you know anybody looking for a Burgundy 1986.5 with 7M-GTE conversion, with current rebuild on engine. I'm selling mine due to the JZZ30 purchase.
