1966 Chevelle

I have a 1966 Chevelle with an automatic powerglide transmission and a stock automatic floor shifter. What I don’t have is the linkage from the shifter to the transmission. I would like to keep the car as stock as possible. Can you give me any leads on where I can get this linkage?

Pick up a copy of Hemmings Motor News at Barnes & Noble or another well-stocked magazine stand.
In addition to listing classic cars for sale, this publication is also filled with ads from suppliers of parts for older cars.

http://www.chevelles.com has a for sale section that you might luck out on.
