Luler Is your Astro van (donor vehicle) AWD I know the two we had for the wife (AWD) were 5 on 5 Bolt pattern, not the car 5 on 4.75 pattern which is supposed to be on the 2WD van. We have never owned a 2 wheel drive so I don't know. If the 4.3 is a Vortec I would absolutely try and swap the 6 with the CPI (Central Port Injection) if possible, the TBI non-Vortec wasn't nearly as fast as our two CPI V6's in the stable of Crap we drive Now. If this is still the plan time changes everything. Hope you found this helpful, Harry
