I kept ALL the 216 clutch, press plate, flywheel behind my 261 and it all worked great. You can get into trouble if you begin mixing these two different era clutches. You can use either vintage but then you have to stay with which ever you go with.
And I love my old 6 volt foot starter, it loves 12 volts.

It's easier to get forgiveness than permission!
