I was wondering where i can start gathering the interior for this car from. I think Postsedan Dan mention one place where it could be bought but dont remember exactly what he said. Also since the car was striped down to a roller when i bought it, Im gonna start gathering date coded engine parts for the car. The trim tag said i beleive it was assembled in may. My question is what would be the exceptable dates for this car. I hope i worded that right. Thanks
