Query: Much needed part

My 2002 Astro never seemed to idle right and I occasionally noticed a miss on the highway but thought maybe that due to was wind or roadway imperfections. It turns out that all along it was this gear. I noticed a fair amount of slop in the rotor when I replaced it and read up on that issue. Apparently, the V6 Vortech is known for worn distributor gears.Since replacing it, my idle is much nicer and that first 1/8 throttle feels more responsive. No more highway miss either.
