Shipping Recommendations

I have a buyer from the Netherlands interested in a pair of Duster fenders I have for sale in the body parts forum. The buyer has asked me to ship to California and his friend will handle the rest. Any suggestions how to get a large package shipped? A box would have to measure 65"L x 22"H x 32" wide, 75lbs. When my wife tries to get a UPS shipping cost, UPS says the box is over size limit. How do people on this site ship large items, or restoration businesses, for that matter. I'm trying to help out a fellow A-Body guy overseas, but keep hitting walls. Any advice is appreciated.
