If you are trying to do what I think you are it's a mistake. I think you are going to put the long end of the capscrew through the torque converter lugs and use the nut for a spacer. I do not see this ending well. There isn't much material for the torque converter lugs to press against. The function of that bolt is to apply pressure to the interface so there is enough friction to push the car forward. It's not like those bolts are primarily loaded in shear. They should be primarily loaded in tension.. Now they are going to be in shear and bending. The flexplate is also going to want to bend.

All this for 0.2" more torque converter engagement? Don't do it. A solid crank spacer would be much much better, but I really think you are overthinking this. Remember the cooling issues a while ago?
