Up for Buy-It-Now is a new old replacement stock center tail pipe hanger, Dorman part number MC 11.  This item was obtained from an old service garage and is not a newly remanufactured part.  According to my Dorman Manual, this is used on the following models and years with the following applications:

Rear Tail Pipe Hanger
1961-1969 Buick Special.....All models
1942-1956 Buick..All models

  The clamp is in brand new, never used condition and is free of any damage.  There is a spot or two of very minor surface rust from many years of shelf storage.  May or may not need a light polishing up before installation.  The original Dorman box is in good condition.
