Thanks for the suggestions, I'm in Townsville and can't find one in any of the wreckers here, plus the plastic/rubber parts that I'm after tend to be completely deteriorated due to sun/heat damage. Will look into the engine swap, I've had the car for 8 years and it owes me nothing, its currently being re-sprayed and the interior is all good so I don't mind spending a bit on the engine to improve the performance.
