All I have had to replace was the AOD tranny.
I love this car. They are normally rare to find but I have found that mine was a NEW YORK Auto show original. There were only five made.
I can understand your love for these cars, I have two 20th's and looking at a third.
I also have a New York Show 20th. I would love to swap info with you and learn more about this soon to be rare car. I knew of another NY, I bet it's yours. e-mail me Precision@potlatch.com.
