I was able to count the number of threads in the installed helicoils and it figures out to be 2 diameter, or roughly 5/16" long.

Mission accomplished! Between the advice from jmorris and 15meter the helicoil went in like it had eyes! I dressed the end of one of my extra screws with my Dremel and a cut off wheel like jmorris said then butted and tightened together 2 10-24 nuts like 15 meter said. The whole thing screwed in until the helicoil bottomed out in the hole in the press. I didn't even need to break off the tab, the screw head tightened just before it bottomed out. I tried a 10D nail with a slot cut into the end first, but the helicoil wanted to stretch on it's way in and then the screw didn't want to thread into it. Thanks everybody!
