Mk 11 Jaguar Flywheel

Hi Just rebuilt the engine and am putting it back together
My flywheel was botched The ring gear was incorrectly placed
I am no considering getting an original 104 tooth flywheel A bit difficulty to find
Could the forum tell me the difference between the 3.4 and the 3.8 Mk 11 and the E type 3.8 I wold think that the latters thesme as the Mk 11

If anyone has a stock Mk 11 flywheel in good condition that miv
ght be an option
Thanks Mike Smith Mississauga Ontario
