If your fiberglass is in good shape or fixable(in your eyes), then shipping the just the sides should be easier to swallow. Either way, it's gonna get broken down for shipping and put on a pallet.
Funny story about shipping one- At one point I had visions of making a half-cab top back in 1999 or so (pre kid). The sticking point was that I didn't want to cut my top, so I found a top for sale in eastern Oregon. Perfect, I had a friend driving out and back, so I set up the sale. When my friend delivered it, I was impressed the little Nissan truck still ran. I had assumed he would break it down and strap the fiberglass to the roof... Instead, he strapped it to the roof fully assembled -facing forward! It was a giant scoop!!! He had borrowed the truck for the trip. Owner of said truck said it was down to a quart of oil from pushing the hardtop in that position. When I rolled the top upside down to get a better look at it, a couple hypodermic needles rolled out of the inner "gutter", so it obviously had multiple uses at one point.
