'81 suzuki gn400 springer front end question

i have a suzuki gn400 that i have been chopping up and i would really like to put a springer on it, i have read that the forks from a xs650 slide right into the triple trees on this bike, i was wondering if anyone knows of any springers that will fit like from TC bros or something

I'm sure this one will fit

google jap bike neck bearing size and for diameter. youll figure out a lot from that classic list. Dont forget that a springer front end is pretty heavy. I have a chopped GN400, and thats one of the things I love about it is how light weight it is. It really is like riding a bicycle.
here is the list on some other site. i dont know who they are, but it was teh first hit in google.
