Im converting my powerstroke to a zf5 manual trans and thought you guys could help because I think a idi are the same way. when I took the flexplate off and tried to put on my smflywheel it stuck out way to far. and there is a extension like thing on the back of the crank and I figured only autos have them seeing how the flexplate is so small compared to the flywheel so im wondering does this have to come off or am I even on the right track? heres sum pics
