Hi,
that's a 1 1/8 inch fork, won't fit. Nashbar used to have tons
of leftover one inchers cheap, guess they're gone. You might call their tech help and see if they have one; and check their returns
section. It's a long shot but worth trying. Keep an eye on the rake,
older bikes had a lot of rake, I'd go with 43 or 45mm, but avoid 40mm.
I like bar end shifters. That's one of my favorite upgrades on an old bike, behind new wheels. Wheels nowadays are so much better than they used to be.
