Well with the flywheel off and counting the teeth I now know I need a 168 tooth flex plate
All I can find out about the engine is its made from 1988 to 1994

I know my engine has a single rear seal so that narrows it down

I am fitting a th350 and when I look up flex plates they are asking if its internal or externally balanced my torque converter has the number 1362650 stamped on it .

Are they all interchangeable or is there a way of telling the difference many thanks in advance for any advice
