Here's another interesting item I picked up from the
www.inlinetube.com guys. They sell "rivet bolts" for the upper control arms. The tops look like the original factory installed rivets but they install with a nut and lock washer on the underside. They are a little tricky to get tightened since they tend to rotate a little and you have no way to hold the top part since it is round. Make sure you use a bunch of loctite on the bolts and tighten them to the 12 ft.lb. spec as listed in the directions.
