as the Commercial Parts Pro at Advance and a fellow Drag Racer, I set up a Commercial Parts Account for all YB members to use at Advance Auto Parts, it's under "Yellowbullet.com" and the Commercial Parts Pro or any other manager should be able to transfer the account to any Advance store in the USA...its a 04 silverado 4.8, how do you get a discount at AAP
