I got mine just now from Summit Racing, based on the post by andrethx, delivered to my door in Jeddah, Saudi Arabia. I figured I'd need it if I should have to replace my 505's ball joints at some point in the future. My mom's old 1982 Talbot Alpine had the same screw-on ball joint design, and I remember just how hard it was to unscrew the old ones and then screw new ones into the steering knuckles and tightening them using a hammer and chisel, just because we didn't have the proper tool. Thank you andrethx!
