I'm trying to upload a photo now, pain in the butt. 

Yeah nothing connected to mine either.  I'm thinking it was simply on all Camaros but only utilized in a single exhaust application supporting that side of the muffler while the single tail pipe exited on the passenger side.

Hey on a side note Gary, your car looks like it got a lot of body color up in the frame rail at the exhaust bracket just like mine did.

Yes, it did... I spent a couple of weeks lying under the car cleaning the bottom side a couple of years ago.  take a look at the two photos I posted of the *unidentified* bracket..  is that the one you are referring to?  I have no idea at this moment what that bracket is for....

Yep that's it.   I've had 2 failed attempts at uploading a picture of it  >:(  I give up.   But you got it.

I think that's for a single exhaust application that uses the transverse muffler with a single inlet and single outlet.  I seem to remember having a nova like that with a similar setup and bracket.

The hangers with the long pieces of steel are the intermediate over the axle hangers for N10. The short complete rubber straps with the L hook on the end are the chambered intermediate over the axle hangers and are retained to the attachment points using this retainer.

This is the early style chambered muffler drivers rear frame rail tail pipe hanger. Original VS Gardner

James,  Thanks. 

Your photo of the drivers side chambered rear most hangar definitely makes it clear that the hangar mounts in the standard location (same as for deeptone hangar), but due to it's design, it supports the tail pipe farther back (which is what
Eric Gardner attempted to explain to me - without photos).. :)  Your photo makes it much more clear.

I'm not sure this drivers side hanger was used for the complete production duration of NC8. Eric Gardner doesn't know. This would need to be examined on original later optional NC8 cars. There is a part number change although it is ambiguous at best.

Gary , Hi isn't that bracket for the cross flow muffler ?

Yes, it seems to be a bracket which hangs the driver side of the stock single exhaust muffler.  I should have gone looking for what this was long ago, when I first wondered what that bracket was for, but since it wasn't used on my car (Z28 with dual exhaust)... I wasn't too worried about it.   The AIM, UPC 8, sheet A4 shows it being used to support the muffler via support hangar ( pn 3953246).

I assume that was used on all single exhaust cars, both six cylinder and V8...??

Gary, I can't believe you haven't got a 6-cylinder car by now to further our research! Shame!

James, thanks for the pictures.  I was lost with the explanations until you posted those pics, now it's clear.

Gary, I would tend to think that it would be a good idea to use that hanger to help support that muffler as well.  The bracket is already there "shrug"  so why not.   Those little tailpipe hangers look a little flimsy back there to me anyway.  The AIM is what I was referring to in my earlier post, has a very clear picture of it being used.

I'm pretty sure though it was a single exhaust application because they didn't have a tail pipe on the driver side so there was no tail pipe hanger over there otherwise.  I had a 71 nova, V8 307 with factory single exhaust, tail pipe exited on the passenger side and I seem to remember the transverse muffler used that bracket and hanger we are seeing on the driver side that isn't used on the Z's.  I know it's a nova but basically the same platform.

Edit:  And I see my pics disappeared  >:(   I was on there the other day trying to load more pics and apparently lost the others.
