The liner-stuffing-heat-&-soundproofing material on the lower surface
of the (steel) engine cover  on our '81 aircooled westie needs
replacing -- what material should I get and where?  It seems to be
held in by a few wire struts - is anything more needed?

Also, the gas on/off knob from the fridge (the rightmost knob) has
disintegrated ... any ideas where to get a replacement?

thanks!
Alan
