How the F do you get to the bell housing bolts?!
After working on early A body bellhousing bolts, nothing is hard after that! If you want a bolt that is REALLY hard to get to, take the top right bolt out that holds an 833 four speed to the bellhousing in an early A body! :BangHead:
To answer the OP's question, I always break the upper bellhousing bolts loose with a box end wrench, then use a 9/16 wobble socket on as many extensions as I can pop together. An air ratchet makes that even easier if you have one. When you're going back in, put the bolt head in the wobble socket with some chewing gum or a wad of tape to keep the bolt head in the socket while you guide it up into place and get it started straight. Then zing it with the ratchet and go back up top and tighten it good with the aforementioned box end 9/16. Good luck, and have some rubbing alcohol and band aids ready!
