shipping bigger parts ??

The most important thing with shipping is package your parts so that they can take a fall from ten feet. I've shipped axles, engines, transmission/transfercase assy.'s and had hood's, doors, headers, heads, and a ton of other parts shipped to me. USPS has always been great, so has FedX and Greyhound . UPS I dont, care for and will not use. If your using truck freight, shop around at least three different firms.
If you need a part, shipping is just part of the deal. Bite the bullett.
