The top bolts are best handled with multiple extensions, I like a big long handle 1/2" fine tooth ratchet because it’s hard to get much of a swing with the handle unless you’re far enough back so the ratchet head is below the tranny tunnel! Or you can try 5' of extensions!

I'm almost certain the bell housing bolts are 19 mm on these cars, a six point Craftsman swivel socket makes getting the tool on the bolt and keeping it on when you're pulling on it easier. A swivel that is tighter rather than looser makes it easier also because the top bolts are kind off recessed in between the reinforcing webs of the bell housing. I know on the auto tyrannies there is one bolt on the passenger side that has very little room around it to get a socket on, if you have a thin wall 19 mm bring it with you!

These manual trannies aren't as heavy as an auto tranny but they still weigh about 60 lbs so don't drop it on your head! When doing this at a bone yard in the past I've used an inflatable $1 beach ball inside an old sweat shirt, get everything unbolted and ready to pull, blow up the ball in the shirt under the tranny, and pull the tranny off the engine and roll it onto the ball. Either unplug the ball's air inlet for use again or just poke a hole in it and the tranny will nicely lower to the ground as the ball deflates. I started doing it this way after I broke one of the exhaust bracket mount rings off the bottom rear of a tranny, it just landed at enough of an angle at the rear and the ring popped right off like it was plastic! It was a pain because no one wanted to weld it back because they where worried about the heat with oil in the case and gaskets near it. I eventually fabricated a bracket that mounted to the bolts that hold the tranny case together to fix things.

Don't forget your 12 mm 12 point socket for the flywheel bolts!
