This arrived in response to 'GTO at speed' from a gentleman who took care of Ralph Lauren's cars:
"...when I drove it  in Montauk NY, the steering box had too much play. I immediately removed the box and rebuilt it myself. Look at these photos--the steering box in the process of being rebuilt.
Now 17 of Ralph Lauren's cars are on display at the Louvre museum in Paris & this GTO is there!"
My thanks to Serge Dermanian for sending these photos and his continuing interest in this car.
