for what vehicle? TG has a kit for mini's, all pro has a kit for 1st gen tacos. other than that, its pretty much custom. its been done though...pretty much 3link + panhards up front. standard link practices would apply.
That trail gear 3-link looks good but not worth the price IMO. Side note, what are good options for axle swaps? I'm thinking full widths would be cool and not much more work considering what needs to be done to get a solid front in there.
