2 piece r. main w/ 1 piece r. main trans

my 355 swap is getting closer buy the day and i just thought of another question... my current 305 has a 1 piece r. main seal and the 355 that is going to replace it has a 2 piece r. main seal. will i have to change anything to get everything to bolt up? what pilot bushing will i have to use? can i use a flywheel off of an earlier 3rd gen? are the clutch kits the same? any info will help

Get a flywheel and pilot bushing for '83-'85 3rd gen. Everything else, get for your model.

pilot bushing
Which actually is the same for your model.

The only piece that's different, is the flywheel.
