starter hits b&m flexplate on 360/904 combo

I am using the same flex plate that is on the motor in your picture. For the 904 I had to use the inside bolt holes for torque converter. So yes. That flex plate was just a little to big to allow the starter to engage the converter. The starter bolted up fine. The problem was the bearing behind the gear drive was just a little to big to let the starter engage fully. The gear drive passed the flex plate just fine.
