Hey Mate,
To be honest I couldn't give you prices but jump on your local website
www.perthrotary.com and the boys and girls on there will be able to help you out.
You may even get someone to take the whole car as is, if you want to sell it. I know there were a few guys chasing a early model rx-7 a few months ago...
Good luck and if you end up parting the car out, let me know and i may come grab some bits!
Cam...
