Default U bolts for sway bars

Does anyone know exactly what size u bolt is required for the rear sway bar bracket mounts. The parts store wasn't really helpful in figuring this out and id like to have a replacement before trying to get the old rusty ones off.

If you're talking about the stock 10 bolt housing, the housing tube OD is 2 5/8" nominally considered as 2 3/4". The GM bolt ( u-bolt ) is P/N 10018208. I had to contend with rust too and first replacements were muffler/exhaust clamp u-bolts, then converted to stainless steel muffler/exhaust clamp u-bolts. If you use stainless steel, a regular steel nut is required as a SS nut will seize on a SS u-bolt.

Thanks for those part numbers. I figured I could try regular exhaust clamps but then I noticed the aftermarket ones had teeth on the spacers so I just wanted to make sure I got the right part and do the install right the first time. I suspect my sway bar has been off before because the clamps don't look like they have teeth. And it's become apparent to me the bar was installed upside down by whoever messed with it last.

i cant believe UMI is pretty much like the only place to get a new bolt kit from and they want $100. BMRs options seem to be weld on for slightly cheaper so not much help there.

I ended up getting muffler clamps from AutoZone. It seems the u bolts they had there are only for leaf springs and way too long. Did the ones you got from advance Auto fit the stock spacer/saddel with the notch? Or did you use the saddel that came with the clamp. I had to cut my own notch in the muffler clamps so it sat on the axel locator like the stock saddel did. The
