U-bolts for 8.75 Swap

Getting damned close to pulling the old 7.25 & sliding in the 8.75 rear. I have the correct shock plates but need to make sure the U-bolts I get are correct. Looks like the housing has 3" shafts so are the correct U-bolts 1/2" x 3.25" x 7.5"

Summit lists these (And of course I just ordered a ton of parts & forgot to include the U-bolts)
