If you get a 4BT from a p-30 with an automatic - does it have a flexplate or flywheel? I have seen the pictures of the wavy steel adapter that one side bolts to a torque converter If you remove this from the flywheel/flexplate, can you bolt a clutch and pressure plate on? I guess my question is - If it came with an automatic, do you need to find a new flywheel to use a manual transmission? Thank You
