help removing instr. cluster

My 69 service manual (Barracuda) says to disconnect the speedo and the left side electrical connectors by sticking your hand up under the dash. Then you have enough slack to pull the instrument panel out enough to disconnect everything else. I removed my glove box and was able to disconnect the heater/AC connections (but it wasn't easy). Also some folks recommend dropping the steering column but it makes a difference if you have a column shift . I'm planning on removing my instrument panel so I've been gathering info. I was also trying to find a vacuum leak in my heater/AC system so I found out about the glove box thing just the other day.
