Hood insulation liner pad
FIAT 124 Spider - 1966-1978
A pair (left and right) of black perforated vinyl with 1/2" (12mm) foam padding.
Some Spiders had space between the hood and its braces to tuck the insulation in, some had places for wires to hold them. Others had neither, in this case the pads can be trimmed and glued in place.
If glued into place, you may want to trim and finish the edges.
