I plan to replace the tractor seat by a HD Police seat on my 2010 Tourist.
Easy peasy thanks to the wonderful tutorial, but unfortunately I live in Europe (France).

Most of the ebay sellers are in the USA, and ebay international shipping policy is now very simple : buyer pays upfront first class service and tax and service on the tax and tax on the service, etc...
Example: a seat with price $135, plus shipment $115 plus taxes $57.
This is not my plan, I'd like the parcel to be shipped like I used to do a few years ago, ie with USPS.
Then if the french custom want to tax me they will do it (or not).
So, what do you think is the size and weight of a HD Road King seat, so that I can estimate the shipment cost in the USPS pricing files ?
Would it fit in this box ?

Thanks a lot for your help.
