About Auto Interior Restoration, Porsche Interior Restoration We have been manufacturing interiors, top, and carpet sets for most models of 356 and 900 series Porsches since 1977. They are offered in kit form for the do-it-yourselfer or for the professional installer. Over the years, our restoration facility has developed what we feel is the most accurate and comprehensive line of interior restoration products for Porsches in the business. Our products are cut and sewn to original specifications using patterns developed in our custom shop. We install what we sell so we know it fits.
