I second that with Sid's axle. at droppedaxles.com While you're at it, send him your steering arms and have him bend them down if you're going 4 inch, and have him plug and ream the holes for a ford modern tie rod end. When you drop the axle 4 inches on a chev, you should really run the tie rods under the leaf versus over the leafs. Lastly, do the same with the pitman arm too and get rid of those old school tie rods. I've called him about 3 times on my project and we end up talking for 15 minutes. A great guy.
