Need an ID on some Exhaust Hangers

[Rat Rod Al]

Any idea what these are for ? TIA

The bracket is a head scratcher for me. Can you find any faintly stamped numbers on it?

The rubber exhaust tips isolator '3466253' was used on many models from 1970 - 1980.

The pictured hangers are for 1972 - 1973 E-bodies with 340 and 1974 E-bodies with 360. Part numbers are 3583778 for the right side and 3583779 for the left side, at the rear of the mufflers.

I’m having trouble picturing how those would work on an E-body. I admit, I have almost zero experience with 72-later e-bodies, but didn’t the dual exhaust cars have the same resonator + muffler arrangement as the 70-71s? Here’s a pic from a very low mile survivor 73 340 cuda with the same 70-71 style trunk mounted muffler hanger with two studs going through the trunk floor. How would the hangers in question work with that?

Thanks for your help ! Much appreciated. I'll see what I can find with those parts numbers!

The following image shows the diagram of the mounting, which still uses an upper stud plate like the 1970 and 1971 cars, from the Chrysler parts catalog:

Wow! Thanks for posting, that definitely clears it up for me. I wonder what drove the change from the 70-71 style. Maybe it made things easier on the assembly line?
