The balancer should be a press fit on 248.
Post the numbers stamped on the boss low on the block between the dizzy and the starter.
The balancer isn't the big issue at the moment, The water pump and pulley are. The pulley will not come off the pump. There are either two broken bolts or two pins in the top of the water pump, can't remove the pulley to get to the bolt behind it, so I can remove the head.
