HELP!! Shipping LBP disc brakes and upper control arms packing question

I have seen posts about members getting everything in to two large flat rate boxes but I can't find any of the posts now.

I have a complete set of spindles, dust shields, calipers, rotors, lower ball joints that are in one assembly plus a pair of upper control arms. I want to save the buyer all the postage costs I can so please share how you packed them with me.
