904 flexplate bolt ?

Hello, in my Dart I have a 360 mated to a 904 lock-up tranny. The torque converter though has a stripped hole for one of the flex plate bolts. Are there any remedies to this that dont involve buying a new TQ? And also for the time being should I not start the car? I dont know if it would throw the balance off enough to harm the engine. Any help is appreciated!

Thanks!
