I don't know anything about that rack or site but proper F racks are pretty rare so it could be worth checking out. The actual rack area seems a bit small though. I have a "from the day" K&G Engineering rack which is very nice and probably the nicest of the "from the day" F racks. There were others from back then but I can't recall who made them. I was lucky enough to have mine given to me, NOS by the way, by a local Honda mechanic back in the 90's. I used to check for F racks on ebay on a regular basis but haven't for a while now...they used to show up but only 1-3 a year. Good luck in your search...
