A Small Note About Upgrades - Part prices for upgrades are with exchange of existing parts for the upgraded parts. In other words, Chevrolet
keeps the original parts and substitutes the upgraded parts. This allows Chevrolet to sell the upgraded parts, as an option, lower then if
you bought the upgraded part by itself. If you wish to keep the original part along with upgrading, you will have to call our toll free 1-800 number
for the cost.
