Size of holding nuts on Univ. Joint\'s U-bolt?

Anyone know the proper size of the holding nuts on the universal joint's U-bolts for a stock 1980 CJ-7? If I had to guess I would say a 12-pt 6.5mm should work but I'm not sure. If anyone has experience with this please let me know. I need to remove my driveshafts for an engine swap and I'm going to have to buy the proper tool. In the attached picture I'm referring to Item 1.
Thanks,
Lee

My 81 has the straps and little bolts they were 12pt and I used a 12pt 1/4" socket.

The only 2 sizes I ever saw were the u-bolt type used 1/2" socket and the 12pt bolts used 1/4" socket.
