So I got my new tips from Moe's/FedEx yesterday. Went to install and existing clamps were seized up (the ones tack-welded to the tips). I soaked them all night with PB Blaster but the heads on the clamp bolts snapped off with very little torque.
The short version of this post....the tips are now installed and look great (will post pics later)! Longer version keep reading....
I had to cut the clamps, pretty effortless with a dremel and they snapped right off. The existing tips needed a quick wack with a hammer and flathead and they broke loose.
Now the problem was replacing the clamps! I was essentially stuck...unable to put the OEM tips back on and unable to secure the new tips in place. In a pinch....those universal stainless strap style clamps worked just fine. Picked the 2 1/2" dia. version and was able to snug everything up. Standard u-bolt type clamps won't work due to this being a butt joint.
In the event that these do not hold up well over time I did some online research on the markings of the OEM clamps. The OEM product is "Norma SEC 60". Further searching and I found a direct replacement part on Walker's website. The part is available for order from Advance Auto here:

I ordered two to have in hand in case the stainless straps fail. I thought I'd share in case anyone else comes along searching for these clamps.
Honestly, with the price ($10.99ea retail, perhaps better in volume)....it may not be a bad idea to include these with the new 5" tips in the future. My truck is only a 2011 and there was no way I could re-use the factory clamps due to their condition.
