1965 Dodge Dart Charger

While finally been able to work on the exhaust system I found out that the muffler has a cut out from the oval format they were made in. Does anyone know if this is for keeping space towards the left rear frame or towards the prop.shaft? I'm not sure which wayit should be bolted!:banghead:

I also wonder about the nuts on the U-bolt clamps should be pointing up or down?

Thanks FABO for all the help.
