I'm working on the exhaust of my 68 Charger and I got a system from Summit. There is an indentation on the body for the muffler to sit up in-but how close should it be to the body? I don't want it to bang when I drive it.

I have seen evil! I have seen horror!
I have seen the unholy maggots which feast in the dark recesses of the human soul!
I have seen all this. But until today, I have never seen such a pain in the ars car like this 68 Charger!

Never really noticed an "indentation" on the body for the muffler to sit up in.  I know original mufflers were "notched" on opposing corners for more clearance between the unibody and the muffler and the drive shaft and the muffler.
