Paul,
Welcome to Chevy Chat. Always good to see a "new" guy here in Chevy Chat.
There's any number of places you could advertise the car.
You could start right here in the "cars for sale" forum. A few more 'down' from where you made this post.
If you were a VCCA member, you could advertise it in our monthly magazine. Called the Generator and Distributor. Usually shortened to just "G & D."
You could also try ebay, your area craig's list, your area auto trader.
Also Auto Trader On-line.
Also Hemming's Motor News....
The list is long. Just poke around on the www and you're sure to find a place you think might work.
Bill.
