What's included for $250?
I just read a post here somewhere where relacing both hubs to stainless spokes was $275 (I don't know if that included new rims either, doubtful)
That's why I went the route you're considering. Modern forks with a better design, modern brakes, modern cast wheels/tubless tires/good tire selection.
For a buy in of $250 it's a very good start.
I understand some Kawasaki triple trees from the same era were identical but with different fork offsets, I may be able to look into that if you need to know.
