The reason I concluded the guibo bolts assemble three inward, three outward is the shoulder on the bolt, no threads, in the sleeve of the guibo. To anyone in the market to replace or remove a guibo, get the clamping band. I had use of a giant channel locks to do the squeezing necessary to deal with placing the bolts. Using nothing but a hammer only guarantees swearing and mangled bolt threads.
I can't imagine fooling with the transmission or exhaust system without a hoist and dolly / lifting devices. Bell housing bolts without socket extensions, swivels.
Trying to assemble what you didn't take apart is interesting, frustrating. I thought the realoem.com exploded views would help, or Haynes, until it became obvious they weren't done for assembly use.
Fooled with the short shift linkage shifting whacky until I realized I'd assembled the shifter bracket with the tail too low. One inch matters large back there.
