Brand new GPS 260 mph speedo, tach and multi gauge with temp, oil sensors - $450 (cost $800 new).
Use these as they are and have standalone instruments that will remain accurate regardless of tire sizes or gear ratios. The speedo has a low voltage feed so it's also ready without any positioning delays. The GPS receiver fits neatly under your fiberglass body since fiberglass does not affect GPS signals. These are complete and very easy to install with no connection to your ECU. Use these with the cups or use them behind a overlaid panel for a more OEM look inside your cluster.
Buyer pays for shipping and optional insurance. Send me a PM or email with your questions.
