You meed dimensions for your goal , fork crown race face to the axis of the wheel. fork rake , blade length
. in other words the bottom of the fork and its geometry matters
and if you get a fork with those ,and there an abundance of steerer tube youre in a good place..
dont disparage a fork thats on the long side its better than too short..
Of course you cab turn the frame over to a custom builder and say make me a fork for this
and I want XYZ handling , and there will be something offered to work.
