What about under pans Marshall? Do any of your cars still have it? Ever see any aftermarket? I'd really like to have all the sound deadening stuff installed just to see how much quieter it will be. My 2.5 is real quiet.
I had to fabricate a new front pan for our SDL, the original was long-gone. I made it out of roof flashing, fiberglass, and fiberglass batting (insulation). It's a thoroughgoing mess now, due to the 603's penchant for oil leaks, but it did quiet the outside of the car down. -- Jim
