Success! After a lot of bending stretching and filing, I was able to get both wheels mounted. I did take the lock nuts off the front wheel and was able to stretch the fork the rest of the way. I think I have shaved about 10 pounds off the bike with the removal of the fenders and chainguard. New tires and innertubes also saved some weight. It had the original Dunlap tires and tubes. At least I assume they were original since Dunlop stopped making bike tires (tyres) and tubes in the mid 1960s.
Still no word from Harris, though. I doubt I will be placing any more orders with them for a while.
Now I am pondering buying a new Brooks Millbrook bag. These are supposed to be more well made copies of the original Raleigh bags. Apparently the reason you don't see any of the original bags is they have all fallen apart.
