After seeing all the work people have done to make their cars as rust free as possible. I decided to do my part. The rear trunk floor pan was " repaired " when I got the flares installed 28 years ago. I thought the body man had removed the original metal and replaced it with a flat piece just slightly above it. When in reality he just welded a piece over the top and left the original pan in place. Although it has stayed dry for these past few years I couldn't allow myself to continue without tearing out the original and the " fix ". So today I get the replacement part from restoration design and have it 90% installed and welded up.
The question I have is the heat shield. Is it needed to provide it's original use to keep heat out of the trunk or is it added weight? |

Go find a wrecked late model Nissan Altima, Honda or Mercedes. Above the muffler you will find these two ply aluminum honeycomb heat shields. Same length as the 914 and about 2 inches wider. Only weights 9 oz compared to the factory heat shield boat anchor. Weld or bolt some 1 inch standoffs under the floor and you have a trick shield and lose some weight. Mercedes uses them just behind the qtr panels and they cost about $28.00 -they are formable.
993's and 996's uses the same material attached to the rear bumper reinforcements to keep the bumper cover from melting. Attached image(s)

That's a Hell of a fine idea. And the OG shield is heavy. |
