Ubolt size

My ubolts are under my rig right now, and it is a good distance from me. Sorry for the lazy question, but I need to know the inside diameter of the ubolts for a Chryco 8.25. I need longer ones, today, as I just added a block and dont feel safe with the current ones. Any help would save me an extra trip home to measure before i go to napa. I am leaving tomorrow for a trip, or I would check myself. Again, sorry for the dumbass question, but it would help. TIA

I believe the 8.25 are 3" dia, D35s are 2.625" and D44 are 2.75", but everyone uses 2.75" on D35s.

Found 'em. Thanks for the info.
