Dart 383 Bell housing

If it has a bellhousing for an 11" clutch, you'd need to change the flywheel and clutch also. They have to stay as a set or your starter won't work. The factory setup is a 10 1/2" clutch. I'll check on that bellhousing number but I don't have the flywheel. I knew a guy with your name that used to have an auto recycling business down here many years ago.
Thanks, Mark
