Hey,Salty Gator.You better check into that Springer.
I checked into the same thing.
Not that same Springer but the only one's I could find put the spring crown in the middle of the steering tube.
I couldn't find fork tubes with the longer spacing needed from the pivot point to the top of the tube where the spring crown mounts.
There's someone out there that has a Springer on an OP Roller but it looks like he modified the fork tubes himself.Kip.
