Top bell housing bolts?

[Tylernme]

What is the best way to remove and reinstall the top bell housing bolts on a 2001 sonoma

The best way is to remove crossframe under transmission to lower it. You can lower 2 or 3 inchs and gets space to access two upper bolts.

Or do like denisGM said and use a long extension with a flex socket..
If the dist is out you can sometimes reach down from the top or reach in from side and get sometimes.
