Thanks Forum Jockey you were spot on which is no good for me. I should have just fitted my coil overs about 7 years ago and would have been sweet. Here's a reply email from the guys at redranger if anyone else is following this thread.

We did purchase Noltec many years ago and re- designed and manufactured all there stock to our range and most of the bushes they sold have been re- vamped into Whitlineplus range found here
www.whitelineplus.com.au
As for coil overs and adjustable strut tops we stopped the manufacture over 2 years ago and ran the stock out and do not want to be a part of that style of suspension.
We are sorry to say we have nothing at all left from the Noltec range and have nothing that we could help you with its a shame you waited so long to find this out as we stayed helping out from the time of the last sale we waited the whole 2 year warranty time before we discarded all the Noltec range in case of situations like this but it has been & years now so there is not allot we can do
