Adaptor1

This is the adaptor I made to mate the Buick 300 crank to the 200r4 automatic. The 300 crank is about an 1" longer than the 215 crank. So that the starter can be engaged I need to have a way to mount the smaller 215 flexplate to the crank. The 215 flexplate has had the centering hole enlarged to fit over the 300 mounting flange. A 300 flexplate is than mounted on the adaptor to engage the torque convertor.
