Ok, I was able to get the correct ACDELCO fuel injection spider assembly from Rockauto.com type in 1999 Astro van and you'll find it, it WILL work in the 3rd generation Astro/Safari's If you watch this video to the end you'll learn that you should have your vehicle run on a computer to have everything synced correctly. SMG Auto did the crank shaft relearn after I replaced this spider injector, he had to do it twice but we got it running right, no more misfires
