Hey Matt. You can internally balance this engine. Save or sell the balancer to someone who needs it if you do not want to keep it. This one year only engine (Sometimes seen in a '72 from what I hear) is a pain to find a balancer and flywheel for us manual trans guys.
Roll the money over into a new balancer for internal balanced engines and if it is a manual trans car, you'll need a standard flywheel. If an auto. trans car, a standard torque converter to suite the stall needs is it. Flex plate is also just a regular part.
The machine shop will take care of the rest. Sorry I can not clue you in on what they will do and charge to make it so. Everyshop differes a bit in price.
