- Transmission. Manual and automatic cars often take different parts.
- Body style. Sedan or hatch, two-door or four-door, cab and bed length on trucks.

Ships by Freight Truck
This item is too large or too heavy to ship as a normal package, so it travels on a freight truck instead of with UPS or FedEx.
The carrier will call you before delivery to arrange a time window, so please make sure the phone number on your order is one you answer. Someone needs to be there to receive it and sign for it.
Freight deliveries are curbside. The driver brings it to the end of your driveway, not into a garage or up a flight of stairs, so it is worth having a second person on hand for anything heavy.
Please allow extra time compared with a normal package. If you need an estimated delivery window before ordering, contact us through our contact page and we will find out for you.
