Usually shipping is the deal breaker for buying or selling windjammers, I've got a few sitting around waiting for the 70's look to come back into vogue.
Lowes sells a double layer cardboard wardrobe shipping box for $10-12 I'm thinking a Windjammer with the windshield removed might ship in one. The next trip I'll bring one home and check it out. It might be a shipping help for those rare guys wanting to buy/sell them. 32x24x24 and I think there's one slightly bigger.
If nothing else, I might be able to store my installed in a dealership but never run dark blue one in a box instead of it getting scratched up.
Any other ideas?
