I have a set of brackets for sale that will fit on the larger 8.8 housing axle (the one from the FX4) I don't remember the spline count since I haven't had a truck in over two years. These are for the short traction bars that fit over the leaf spring. If you have a set on your truck already you can add these for extra strength. If you are a newer member just look through some of my old posts to see what i am talking about with the different size axles.
This is just for the axle brackets not for the complete set of traction bars.
$10 shipped... i basically just want to cover shipping costs
