5.9 Magnum flywheel - DIY with bolt-on weight??

Wow, I'm late to this party.

Looks like you bought the MP specific flywheel for your swap, correct? If so, that was the best path to take.

Just to clarify some, the only issue I am aware of when swapping a Magnum into an early car with a manual is if you want to keep the EFI. The 143T flywheel was turned down and a 130T ring gear pressed on because there is no available flywheel with the right ring gear and the notches for the crank sensor. So, if you want to keep your A833 but run the factory EFI, you have to find some Frankenstein setup to put it together.

If you are going with a carb, buy the MP piece and bolt it on. Done deal.
