bolts for 88 trooper flex plate

I have an 88 trooper, automatic, and had to replace the flex plate. I am hoping someone knows the size bolts used to bolt flex plate to torque converter. I have some bolts but I don't think they are the right size. I started this project over a year ago and had to put it on hold and of course never put a label on anything important (like bolts and where they belonged)

Thanks,
Jim
