Going to swap my old 258 w/ 4.0 head for a 99 model 4.0 in my 84 CJ-8. Already have the mpfi setup, just going to use it along with the TF999 trans. Question is will the flexplate and starter both work on the 99 4.0 engine? I've been told that I need the flexplate that fits the engine and to drill it to fit the trans. torque converter. Just need to know which is correct. Thanks
