Hey JohnSkagg,
In relation to the clearance between your front tire and your fork, it might be exaggerated if you've gone with a 700c wheelset? It looks like a nice old frame so it probably originally came with 27" wheelset. The difference is minimal (700c = 622mm, 27" = 630mm), but with a set of 27" wheels and some fatter old school tires, it might make a difference to that clearance.
