Ask the question on the "What Do You Need For Your Viper" forum?
NOTE: 20+ internetters went banko from 2008-2010, and some OLD Corsa stock is floating around.
ASK CORSA about the 4 improvements they made to that part number since it was introduced vs. Old Stock?
ASK CORSA if the vendor you choose is a Corsa distributor, so you have a lifetime warrantee.
"Lowest Price" may not get you a lifetime warrantee, the latest iteration, or any tech support, or local installers.
I can tell you a dozen incidents of "Low Price" offerings that have NO STOCK, No updates on old web prices, NOT corsa distributors, and DID hang owners out for weeks....and then voided / refunded the sale. All to save $50.?!?
Know Your Vendor!
