I'm looking for pictures of an early version C-10 seat (without the step-up at the passenger section) that's been converted by Russell Day-Long as a 'solo' (where they don't modify the passenger section, they just re-cover it to match the modified front section).
The C-10 pics on the R D-L site are the later stepped seat or are dual modified (driver and passenger section modified).
Check my Concours album. Thousands of pix. Too many for me to browse for you. grab a brew (or 6), settle into your favorite chair, and flip through it.
