Nice looking bike like that deserves a really good looking fork. Finding out a new fork is not fitting is in fact quite humbling. Ya keep thinking back I should have checked this or that and what can I do to fix it. Some times ya just gotta scratch it off and start over. That might be best and you can paint a new fork to match this winter during down time.
I once ordered a new steel fork. Trimmed it, primed it, painted it, and at assembly found it was a 700c instead of a 27"... Ha... It has been so humbling that I dare not mention it till now...
