I've gotta ship the front brake setup of an integra to Pensacola. Spindles, hubs, rotors, and calipers.

Which would be cheapest, do you think?

Put it all in one box. (I don't think they're together-weight is > 70lbs.)
Split the two spindles in two boxes.

Also, which would be the cheapest method?
USPS
UPS
DHL
FedEx
Truck Freight

Trying to figure out how I'm gonna send these things.
