There was originally material in both places. The seal between the glass
and the bezel may have originally been "dum dum" rather than an O-ring. The
seal between the gauge and the dash was definitely supplied as a ring, but a
modern O-ring is only an approximate substitute. The original was firmer,
less stretchy, and I believe was rectangular in cross-section. Justin
Wagner recently told our local club that there is a VCR drive belt that is a
better approximation than an O-ring. The ones he had sure looked good, but
unfortunately I don't know a part number or supplier offhand.
