the Model A starter drive used 5/16" bolts and they break all the time. the V8 starter drive uses 3/8" bolts, I run the V8 drives and have not broke a bolt in many years. check and see what bolts you have. if you are running a 6 volt starter on 12 Volts it is going to engage hard and that is hard on the drives and or the bolts.
