I'm trying to replace my clutch and need to remove the transmission (Ford 3 Speed) and Transfer Case (Dana 20) as one unit. I can't seem to figure out how to get my T shift post on the transfer case off so I can slip the unit back. The post sticks up through the floor and is held on with a long bolt through the transfer case casting. I can't slip the bolt out because the tunnel is blocking it. The only thing I can come up with is to cut a small hole in the side of the tunnel that will allow the bolt to slip out. I need so sage advice please.
