We got a reply from Katie at Land Sea Services in Golfito and they will accept shipment of the turnbuckles. They sent us an address and said if we weren't in a hurry, US Postal Service would deliver economically. Gene emailed Rob Friedrich at American Rigging Supply and they have the turnbuckles in stock; no four week wait. We will email American Rigging Supply manana and have them ship to Golfito. We should get in about the same time as the parts. Sweet!
