Torque converter, flex plate bolt applications

Thanks guys, yep as u described. I just checked spare tc and its 5/16"(need to find 2 more) and flywheel to crank makes sense as they would be from the 69 4spd.
Thanks!
BTW......I've got a ton of those TC and Flexplate bolts if you need any.

Left torque converter to flex plate. center are Flywheel to crank. right are flex plate to crank.
