[DeTomaso] Looking for parts

[Tomas Gunnarsson]

Maybe so, but if you run without the muffler support entirely the exhaust pipe will break which indicates that the rubber supports the weight of the muffler to a notable degree. The rubber parts that I replaced on my car had bolt holes with a look similar to stretched earlobes without the plug in it. The new ones I installed with proper hardware have been on the car since 1998 with no signs of fatigue. The old ones were of course lacking the proper washers.
