ANNOUNCES ITS NEW AERO-RIVET-II CLASSIC CORVETTE RIVET TOOL Patent Pending – Made In USA The ultimate solution to the rivet setting dilemma for 1953 through 1982 classic Corvettes. Through extensive testing we have developed our new AERO-RIVET-II Tool, a precision rivet tool for classic Corvettes.   Features:   Allows for the precise, factory equivalent setting of steel, aluminum and brass tubular and semi-tubular rivets used on classic Corvettes, such as those used on air vent doors, re-bound straps, window channels, vent windows, heater boxes and ignition shielding ground straps, without damaging the material being riveted. Body and drive bolt design allow for close clearances of tool to work piece. Enhanced tool functionality provides for setting rivets from either end of the tool and the ability to set small (3/16” dia. or less) solid aluminum rivets, such as those used on C2 rear valance panel nut plates. CNC machined from 6061-T6 billet aluminum and uses high-grade 4140 hardened steel components for greater durability and longer tool life. Overall size is 4” x 3.5” with a 2” wide by 2.5” deep throat opening. Supplied with three depth adjustable bases, one each for truss head and flat head rivets and one for setting small rivets; and four interchangeable drive bolt tips, one each for setting large and small rivets and one each for truss head and flat head rivets.

All service work is done in-house by Bryan A. Thompson, founder of the Corvette Electronics website, batee.com. This is not an exchange service - we return your repaired components back to you! The speedometer / odometer tests may cause your odometer mileage to increase by a small amount. If you don't want this, let us know and we'll skip those tests. Removing the Components - Removing the 84-89 Cluster: Click Here The 1986-1989 Programmer is a small black box, about 6" x 6" x 2". It is located in the drivers side footwell, just above the gas pedal. Follow the colored vacuum lines to the programmer. The silicone block with the vac lines is held on with a push on keeper around bolt in the center of the vac lines. Unscrew that keeper with needlenose and then remove all vac lines as an assembly. Removing the 90-96 Cluster: Click Here Removing the 90-96 HVAC Programmer Module: Click Here Removing the 90-96 HVAC Controller Module: Click Here Shipping to Us - Print your name, return shipping address, email address, telephone number, model year, odometer reading and a brief description of the symptoms on a piece of paper taped to the cluster. It is common for us to get components with four or five return addresses attached. People include a home address, a business card with work address, there will be a third address on the box that corresponds to the UPS store where it was shipped, and Paypal gives us a fourth address from ten years ago. We won't be able to return your cluster until we establish the actual address to return your shipment, so please explicitly tell us what the return address is! Make sure the instrument panel is surrounded by packing peanuts or bubble wrap at least two inches thick on every side. Newspaper, shredded paper, rigid styrofoam, and air bags by themselves don't provide adequate protection for the cluster. Don't ship in USPS Priority Flat Rate box - it doesn't allow for enough packing material! No, a dog blanket or Christmas tree skirt isn't good enough, either. Yes, we have seen all of these! Ship the cluster to the address above, then email us and let us know that you've shipped a cluster to us for service. Please don't ship to us via Fedex. Fedex in my town is completely unable to deliver a package to us! The Repair Process - We offer a free, no-obligation diagnostic service. When your cluster arrives, we will diagnose it, email a repair total, and wait for your approval before doing any work. This typically takes 1-2 business days from the time we receive the cluster. If you approve the work, it typically takes 1-2 business days to complete. If not, there's no charge other than return shipping. When we have completed the repairs, we will run tests and then email you with photos of your repaired cluster. This won't happen if we don't have an email address for you. When we have completed the repairs, we will send photos of the working panel if you provided an invoice, and we will send an invoice through our credit card processor, Paypal, to the email address you provide. No Paypal account is required, and this invoice can be paid online securely. It is common for us to get components with four or five return addresses attached. People include a home address, a business card with work address, there will be a third address on the box that corresponds to the UPS store where it was shipped, and Paypal gives us a fourth address from ten years ago. We won't be able to return your cluster until we establish the actual address to return your shipment, so please include that! If you pay for the repairs with Paypal, please make sure they have your current address information. They provide that information to us, and we print shipping labels from the info they provide. We are forced by their policies to ship to the address they provide to us, so please make sure it's the correct address! When we print the shipping label for your components, the system will notify you of the tracking info. This won't happen if we don't have an email address for you, or if your email provider flags Paypal as Spam. Payment - We accept credit cards, Paypal, and US Postal Service Money Orders as forms of payment. E-checks, personal checks and non-US Postal Service Money Orders usually take weeks to clear, and delay the return of your repaired components. Customer is responsible for actual return shipping charges (typically what you paid to ship the component to us) It is the responsibility of the customer to file shipping damage claims. batee.com will provide documentation and logistical support upon request. Parts Orders - We ship all in-stock parts orders within one business day. We will gladly replace defective bulbs within the first 30 days after the sale. In the unlikely event that an item you order is out of stock, we will contact you and let you decide how to proceed. We offer free online installation instructions and videos. These are linked from the product sale page, and are printed on the label on the product package. If you have questions, feel free to email us. If you purchase with Paypal, please make sure they have your current address information. They provide that information to us, and we print shipping labels from the info they provide. We are forced by their policies to ship to the address they provide to us, so please make sure it's the correct address! Shipping prices listed and free shipping offers apply to US customers only. When we ship, the shipping label printing system will email the tracking information to you. This won't happen if we don't have a correct email address, or if your email provider flags Paypal addresses as Spam. International Customers - We love our international customers, and routinely ship parts and repairs internationally. We can't return your calls. It costs us over $4 a minute to make these calls!

Our high performance Z-GS brake rotor provides the following major benefits: Better stopping power. Improved cooling. Reduced warping and cracking. Superior gas elimination. Enhanced appearance.

This special pattern eliminates gas pockets and lowers the potential for "carbon smearing" or "transfer" from the pad material to the trailing side of the slots in the rotor. Finally the rotors are gold zinc dichromate plated. Cost (set of 4) for both C4/ZR-1 (88-96 heavy duty brakes only) and C5: $365.00 plus shipping. Level II Z-GS Upgrade Service - Complete New Upgraded Rotor Set. We perform all of the operations under Level I, except turning, but instead of using your current rotor set we use new GM rotors. Cost (set of 4) C4/ZR-1 (88-96 heavy duty brakes only): $690.00 plus shipping. Cost (set of 4) C5: $625.00 plus shipping. host1 Tue, 27 Mar 2012 18:02:00 GMT f1397696-738c-4295-afcd-943feb885714:97
