I know that ORS has a few options for you as well. They are working on a triangulated front and rear. But Highly recommend that if you do a 4link in the front that you have full hydro steering. Curretly they have a 3link with panhard for the front. They are also fine tuning a 3 link with panhard for the rear so that you can keep the stock gas tank if you want.
i have 2 requirments, stock gas tank, and retaining my x-over, so 3 link w/panhard is probably the way ill go
