lost rack(gear) shaft coupler connection to steering

When I sent my core down the road, I sent the thing that fastens it to the steering shaft . What are my best options at this point. I see where I can buy a Flaming River joint for 100 bucks. It shouls fit. Or I could go to a junk yard, i guess. local parts stores don't have them. Im scared to ask the Ford dealership, as it might be cost prohibitive. Are there any great solutions ?
