Default Does this Exhaust Hanger have rubber insert

I noticed that the exhaust hanger near the gearbox seemed to be loose in the part it hangs from, and I suspect it should be set in rubber.

Here's a picture with red line pointing to the part and the relevant part number pasted in above -


Does anyone know if it should have rubber or not?

Is that for a LT1 car? I know my '85 didnt have rubber bushings on the cat hanger, only the muffler ones.

G'Day Rod - thats the one- so there should be rubber in there - thats great to know. Should be easy to get some more rubber and refit - how heat resistant should it be???

Thanks

Ok, not sure what I'll use, maybe I can get some silicon ? any suggestions?

At least I know now where the vibration is coming from on acceleration!

Just bought one for my '92. It's a metal bracket that bolts to the DS of the trans and has two springs with attachment plates that hang done from the sides. There are no rubber parts and it is NOT a rigid mount.

I used coolant hose to stop the knock between the frame and pipes of cars Ive had before. But that was close to the back of the car.

Does anyone know where you can Buy that hangar. I'd settle for Either design - the rubber isolater (early design?) or the dual spring one. That (on my '85, Rubber) hanger is not available Anyplace I've looked, and hasn't been for several years now. I've lived without it for nearly as long as I've Had this car, coming up on nine years now

Corvette Central pn#324441 is the hanger/isolator at the back, behind the mufflers (one on each side). It is NOT the central hanger off the transmission tailshaft that we are talking about here.

Still looking..
