Mine's all custom made from parts you could cut off of an 80 series axle in a junk yard and a piece of schedule 40 pipe.
Front leaf-spring shackle, rounded for clearance:
Sleeve around the factory x-member and a through-frame tube intended for a shackle reversal, but we didn't use it (for that):
Misc brackets off the 80-series rear end when I cut it down:
Pinned instead of welded in case I want to replace the link ends some day and welding would burn the rubber.

Here's a picture when I was mocking it up. All that extra tube is inside the pipe, in case you were worried it wasn't strong enough.
The front link is pinned through an oblong hole so it can rotate a bit. I love that it uses mostly Toyota parts.
