Can you just remove a flex plate from a 4.0 engine and put a flywheel on it so I can bolt up a manual transmission to it?
I believe you'll need to add a pilot bearing to the crank.
Yes a flywheel will just bolt up but as above you'll also need to install a pilot bearing for the manual transmission's input shaft.
I was just saying I'm doing a complete rebuild and putting a new crank in, so I should be good.... Thanks for the feedback
