I just reinstalled my fuel tank and then I read about checking to make sure
the sound dampening pads were in place.  I didn't remember seeing anything
when I took off the straps, but I did find, on the ground under the car, two
identical looking items that might qualify.  They were about 1/16 to 1/8
inch thick, 3/4 inch wide, 1 1/2 inch long.  There were only two, and I
can't find them now.  I just lowered one of the straps to see if there were
any pads fixed to it, but there weren't, and I  don't rermember seeing
anything like that.  The strap(passenger side) when tightened in place, is
not completely tight(the gas tank is empty) and I can wiggle it a bit.  Not
so with the other side.

Should I make up a shim of somekind(cardboard or piece of wood) to act as a
sound dampner/shim.  How important is this and what kind of noise could
result if I leave them out and they are necessary?
