There's a few on Ebay right now, but you will see that most of the Corvette guys on there want as must for used as you can buy new (with a discount). I' sure you have done this but check the Vett forum's you can sometimes find some there. Good Luck
Thanks. I noticed that they are all priced quite high. I have a possible way to get parts at cost so I am going to check that route out and see what it turns up
