It's not a problem if you don't know all the information for the form. We keep very good notes! Most GM cars (including Camaro/Firebird/Corvette) have a 5 lug on 4.75" diameter bolt pattern and have M12x1.5 factory studs. Our adapters have heavy duty M12x1.5 studs and lugnuts standard. 1/2-20 SAE is available with custom adapters. The standard adapters we keep in stock are 1.25", 2", and 2.25" thick with a 5 on 4.75" bolt circle. All other sizes and bolt patterns will be custom machined for you. Please contact us if you are not sure. Custom adapters are not returnable, so please double check your measurements.

Shipping Rates are $10 for one pair of adapters and $18 for two pairs. COD payment is an option, for an additional $7.50 for in stock, standard (no custom) adapters. We can ship adapters overnight or 2nd day, however the UPS shipping fee will be more expensive. Hawaii and Puerto Rico requires air shipment. You can get a general idea by visiting the UPS Website and using 15 lbs shipping weight per pair of adapters. Our zipcode is 06119. We also ship to Canada through UPS and USPS, and shipping will be quoted per order. Custom orders generally take 10 days to machine, and cannot be COD.
