07 FXSTD front wheel swap
Restoring an abused and then mothballed Deuce. Shop sent me an aluminum mag wheel they said would fit, as I don't trust the rusty one on it to ride to a shop, and I have the tools to swap it, just not the knowledge apparently. The spacing's all off by just enough to make things weird. Bearings fit, so at least there's that... but the brake disc is a good 3/8 shy of the caliper, so the wheel sits significantly off center and rubs tire on fender, or I need some version of spacers. So is there a "best practice" when it comes to making up this distance? I'm leery of installing spacers on the caliper mounts, as that gives the caliper more chance to tweak and end up binding up when it does. Spacers between the wheel hub and the disc seem sketchy to me, but maybe practical, and a new wheel hub seems like the likely route (though obviously more expensive). Why would a shop be sending me a wheel that needs all this and saying it would fit if I need to buy a new hub? My understanding is that the FXSTD has a wide glide front end, but also that nothing fits a Deuce... ever... so I guess I shouldn't be surprised.
What's the normal width for a wide glide front wheel from center to disc mount? What method would you folks recommend for aligning the brake disc with the caliper? (Disc spacer, caliper spacer, or new hub/wheel/fkitall)
A few disclaimers: First Harley, so I'm a bit inexperienced with HD-specific nomenclature. Explanations are welcome and I won't get pissy if you assume I know nothing. (You may be right!)
Thanks for your help!

Simply put, yes. The way I got my measurements for the disc and caliper not lining up was by centering the wheel on the axle with no spacers at all and the caliper loosened to move freely in its mounts. The distance between the caliper and its mount holes when the wheel is centered on the axle (no spacers in place) is 5/16.

Personally, I center the wheel in the forks/fender first, with correct spacers, etc.Then use a disc spacer to move the disc back to relative center with the caliper once the wheel is perfectly centered. Over the years I have accumulated and made several disc spacers that allow me to mock it up, then make disc spacers or purchase to exact needed specs. Make sure disc mounting bolts are long enough for proper thread engagement into the hub accounting for spacer thickness.
So, short of it, sounds like you need a 5/16" disc spacer with appropriate length mounting hardware. You can purchase those chromed and ready to bolt on...

My personal preference is to steer clear of rotor or calliper spacers, which aren't really required if you do the rotor/calliper alignment the way it was done from the factory i.e. using the axle spacers.

Vulcan Works Spacer
Looks like the ticket, but I'm not sure if my info is accurate. Is there a difference in hole sizing or spacing between the rear pulley and disc?

No dog in the fight. But you listed a "pulley" spacer?
Need "rotor" spacers. My bad if the link was off.
I would also want to "center" the wheel and space the rotor or caliper.
Having the front wheel 5/16" off center "might" not be wise????
My 85 factory service manual had specs for proper wheel alignment.
Never checked my Deuce manual but did turn some nicer tapered spacers.

I'm centering the wheel first and foremost. The problem is that I either need to space the caliper in or the rotor out by 5/16 after the wheel is centered. Lead time on custom machining a front rotor spacer is pretty significant, so I'd rather buy one if at all possible. Suggestions?
