I'm swaping in an 8.8 and I've got the metal I'm going to use for the top plates, but I'm wondering what size hole do I need to drill for the head of the spring retaining bolt. Does anyone have a set of plates out they could measure? My 8.25 is still under the jeep and I'm not wanting to tear it out until I get all of the parts together for the swap. Thanks for the help.
