Muffler hanger bracket

I'm changing my muffler out to a new Aries. My question deals with the hanger bracket that attaches to the frame. The original bracket has one flat side and the other side has a 90 degree upset on the parrell side. When the bracket is correctly installed which side is installed in between the frame channell?
 
Did you get the hanger from Aries? They have one with a lining that allows the muffler to slide in the hanger preventing the muffler from cracking.
 
If it is a steel Aries, you don't need the clamp with the internal lining, If it is the stainless Aries you do or as Mike states above it may crack. With either bracket, remember not to squash the clamp, only tighten till the cotter pin will go in.
 
Also remember to leave this clamp loose until the manifold connection is tight, them go back and snug up the rear bracket.
 
Confused now,my original clamp is held in place by a bolt. Don't see where a cotter pin could be used. Also the muffler is the steel one
 
Here is a picture;

A note about the lined muffler clamp. I put one on my Aries muffler before my trip this summer. after 1320 miles the bottom of the lining was worn down to the metal. It had worn a groove in the tail pipe. Huge waste of money.
 
To clearify one thing...whenever this subject comes up someone seems to mention the fact that the pipe grows in length as it warms up.
For this reason the clamp needs to be neither tight nor loose...just a happy medium so the pipe can move slightly with expansion/contraction.
This is the reason for the cotter pin. Set it for a slight drag, then install the pin to keep it there.
 
Keep in mind that if you buy the cheap taiwan clamp it comes with a carriage bolt . If you buy the USA made clamp (either style) they come with a hex bolt and cotter key and castle nut so they can be installed correctly (not tight).
