^If you think it would do any good, I'd appreciate it. I measured the Standard's front hub width at 6 3/8" - I'll ask the seller to measure the Springer's and seen if it's the same.
If it all goes to hell, I guess I could always rebuild the wheel with the Standard's hub and the Springer's spokes and rim. I've never done one, but you got to start sometime.
Thanks for your help, anotherguy!
