They actually work pretty well to keep the heat inside, plus they eventually get somewhat wet with oil and help keep the HEs from rusting. The HEs tend to rust out at the front end, however, where there is no insulation. There was originally a metal "skid plate" at each lower front corner, and a metal strip along the bottom. These were held in place by 4 metal straps, which have probably been replaced by cable ties after the straps rusted away. The original straps have a special kind of "buckle" which can be reused if you have some kind of metal strip to replace the strap with. I have a number of stainless and titanium (!) straps that I cut from scrap from my previous job, but i don't have any spares of the special buckles. You could probably just use ordinary 3/8" wide hose clamps, but they would have to be long ones. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
