These are extremely rare optional wheel discs. They cover the spokes to give a more stream lined look. I had several sets spun years ago using a original as a guide. A widow lady has given me permission to sell a set they never used. They are not plated. The set is 6 discs set up for 17" wheels. I now have a factory photo available to email.
I'm not sure if they fit LaSalle wheels. Pics available from a friend in the club. Please feel to ask questions, Price is $1400 plus shipping. Please contact me directly at bobscads@comcast.net
