Be advised the upper bell housing bolts can be a RPIAS. The way I did mine was to remove the drive shaft support the transmission with a floor jack, remove the trans cross member and lower floor jack to gain access to the bolts with a long extension and swivel joint. But than that was not as easy as it sounds as the bell housing bolt heads are not very thick and the socket has a small chamfer at the end of the socket and had a tendency to rotate of the bolt head. I used replacement bolts that had thicker heads on the re-installation. I also got some longer bolts for the bell housing to use as jacking bolts to line up the bell housing to the block and once I was close enough to get the correct bolts in I switched out the long bolts.
