I am looking for parts. I have contacted a few places in CA, but have not gotten good responses back. This has been a project car for the past 5 years. It is driven, but needs a bit of parts to get it back in shape. Rear spoiler contoler , 911.618.112.00, is one of the easy fixes if i can find one used. Also the front left AC radiator and entire shroud. I am looking also for where i can buy a good wiring diagram for this car. If anyone has misc parts also for this car let me know. Im sure there are many knick/knacks i also need.
