My '94 RS America is coming apart for a complete rebuild. The body will be stripped and painted, and all mechanical systems rebuilt or refreshed. I have the manual steering rack (964.347.011.02) which I intend to keep - but this is the only component that I cannot seem to find parts for. I'd like new boots and seals at the very least, as this rack has 114k miles on it. If there is a reputable vendor who does rebuilds on manual racks, or a kit of parts, I'd love to get some pointers. Thanks in advance to this great community!
