| This listing is for a used Speedometer head for a 74-78 z car. It is guaranteed to be in good working order for at least 90 days after the date of purchase. There is a refundable core charge that is not included in the posted price. The core charge will be added automatically by our store at the time of purchase. You have 90 days from the date on the receipt to return your old unit. To get your refund, the casing and lens must be in good shape, it must be properly assembled, and it must be rebuildable. Be sure to let us know the specific year for your z, there are 2 different styles of lettering on these cars and we want to make sure that you get the correct one. Note: the trip odometer cable is not included with these units. If you'd like your unit to be rebuilt, we do have a company that can usually repair your speedo for an additional charge. Call for details. Last update 10/11 |
