I am over here in California, and a guesstimate on the shipping is about $50.

Used leaf springs aren't an issue as long as they aren't cracked, and new ones aren't terribly expensive, but not cheap either.

I found some new ones for $225 each, plus shipping.

I would be willing to sell them to you for $250 for the set, and I would include shipping (basically $200 for both).

Only recommendation would be to buy new bushings when you install them.
