I have a 98 S10 and I was told that I will have the firewall/bulkhead issue when I go to change my clutch. I know a few GM techs and they all say the samething about it but they also tell me that loosening up the motor mounts will help in getting the tranny to hang down low enough to work past the obstruction/firewall/bulkhead. One of the guys told me to unbolt and remove the motor mounts from the truck then set the engine on a small pce of wood on top of the X-member. I will just figure it out when the time comes but good luck when you go after it.
