Here's a bit of a summary of what you'll find in the link Spencer referred you to:
I got the hydraulic top link from Gearmore in CA. The part number is T3x8-18. The total cost was $270 plus $20.28 to ship = $290.28. I got the hoses and fittings made locally for $32, so the total cost was $322.28. To order one, call Eric at Gearmore, Ph 909-548-4848. They have different lengths, so you'll need to measure what you need and the size of the pins.
