Default U-bolts? Trying to order the correct ones

I am trying to find the correct replacement U-bolts for my truck, and Napa has a ton of them. I'm not going to remove one just to take it in to Napa to match it up (for a few reasons).

If anyone has the Napa U-Bolts and knows the part # of the ones they ordered that would be sweet. Thanks

i know its a roundtop lol. ive had them off and back on so many times im way overdue for new ones. thats interesting, i got under the truck and my measurement came up 2 13/16" and napa has part 6504026, the spec for the inside edge length is 2 and 13/16". And then they have a ton of 3" wide ones. dunno if that little difference even matters. but im going with the narrower ones

Nah all our u-bolts at the shop are 1/8" larger. They wrap around the axle when you torque them up so they arent so tight to get them in.

I see.
ok well scratch what I said in my last post, I had to go to Napa and try out like 3 different ones before finding the one that fit just right. The correct Napa ubolts for my Ranger (8.8 axle) are part # 6504003 and they are the only ones napa has that perfectly match my stock ubolts in dimensions. These are 2.88" wide on the inner edges. (The 3" ones seemed alittle too wide, and the other one I posted above that is 2.81" is too narrow.) Brinker I guess I could run some 3" wide bolts but these 2.88" bolts slid into the plate exactly like the stock bolts, without me having to compress them to get them in the holes on the plate.
Also, the 6504003 is the correct 1/2" thickness like the stock bolts.

So the 6504003 is the only napa ubolt I found with a 2.88" ID. But it's only 7" long. That's perfect for me because I don't have blocks. But I know it may not be long enough for the 4x4 guys with factory blocks who need at least 8-9" long ubolts.

Does anybody know where i can get new U-bolts. I currently have 2.5" blocks but i'm going up to 4" and can't find long enough U-bolts. do they have to be the flat top style or will round top style still work?
