There are one or two manufacturers of seat kits which are thought to make good products. In leather. Fairly reasonable, last time I checked. But then there is the problem of finding someone who can and will install them. My sport seats are (from memory) from the seventies. There are two generations of sport seats that could have come on a 911SC, I think, and mine are the earlier ones. They look a bit "heavier" than the later (Carrera-era) sport seat designs. Anyhoo....according to my research, my seats would need to be substantially disassembled in order to install the seat kits, and the mechanisms which must be disassembled are not simple to reassemble unless you pay great attention to their configuration during disassembly -or- the installer has substantial experience -or- BOTH. That said, an experienced, careful upholstery person could likely install those seat kits with relative ease.
