Early 70s CJ5 Dana 30 u-bolt size...2 sizes?

Ok. I found a wierd one. I'm installing my 2" add a leaf suspension and started to work on the passengers side front tonight. As I began removing the U-bolts (cut off saw technique ), 1 of them was on the axle tube as normal, but the inside one was on the diff casing itself were it steps up off the axle tube. This would require a different (larger) size U-bolt. Seems a bit strange to me.

Can anyone confirm this or take a nice close up picture of the passengers side set up?

Thanks!

 

Dana 25, 27, 30,.....
they're all that way
3 ubolts over tube will be the same
1 over the pumpkin is wider
look at passenger spring plate and note the hole spacing

 

x3 that is normal.

 

Gotcha, thanks. I just looked at the spring plate. I'm kinda slow sometimes......

Anyway, is the inside diameter 3 1/8"? Just want to be sure since I measured it after a few.......ah.....barley pops........

Thanks!
