3.2 liter engine w/ G-50 to 915 Trans. Conversion?

I am going to put in a 3.2 engine in a 1976 911. What kind of flywheel do I need to put the later engine in to my older 911? The 3.2 had a G-50 transaxle and I would like to adapt it to my 915 trans. What parts are required to complete this swap? Any info would be much appreciated. Thanks
