Hi Keith. I'm sorry but I can't help with your question and I want to make sure it's in the correct forum to solicit help.
You've listed your Vette as a 1999 model, but referred to it as a C6 and posted in the C6 forum. Since the 1997-2004 models are referred to as C5's, I will correct your thread title AND move the thread to the C5 forum... I just need you to verify that this would be a correct assumption on my part.
We'll get you there!
