Thanks for the tip. Very hard to locate the noice unfortunately.
I've had the car since new - 94 with the transmission so far the major work. It was done by Kelly at Torque Transmissions at Chullora. Kelly was an expert but has since sold the business to one of his employees - not sure of his strengths!!

Keep me posted about the next meet and I might see if I can bring my beast along.

In the meantime I'll monitor the noise, wait for some more tips and hope no more damage is being done!!
