How the F do you get to the bell housing bolts?!

Recently pulled a small block 4 speed bellhousing out of an early A in the junkyard. I tried about 7 different 9/16ths wrenches on the bolt closest to the distributor. (some brand name and some chihesium crap I had modified for other difficult bolts) and sockets and even some 14mm and none worked. I was getting ready to drop the whole k member and work on the bolt on the ground until my dad told me to try his 9/16ths from his snap on roll up kit the next day. I decided to listen to him while also taking my tools to tear apart the car... The snap on wrench worked like butter.
Ask around to your friends for their wrenches, and maybe shoot some penetrating fluid on them to sit overnight.
Good luck!
