Fatbob front end conversion FXDC
I have a 2010 Superglide custom and I want to make the swap to a Fatbob front end for the better handling and the dual disc. I have a few questions.
1. What all exactly do I need?
2.will I need to swap front fenders?
3. Will the rear wheel and tire fit

The Fat Bob lowers have unique caliper mounts that make fitting other Dyna wheels problematic. Low Rider lowers are easier.
If you want the FB wheels, then FB lowers are the ticket.
Axle spacers to match donor front end. (FB lowers, FB wheel, FB spacers...or...LR lowers, LR wheel, LR spacers)
I fit a touring front hub to mine, but it required some machining to fit my FB lowers.
Dual brakes means new master cylinder, lines, RH caliper, rotor(s), and all associated hardware.
Wide trees (49mm), fat bob has a tiny negative rake, wide glide has a little positive rake, not sure about Low Ride (if it's even a wide tree)
Fender to fit wide trees
Not 100% sure about headlight interchange, but I'd strongly suspect they all swap easily.
I think that's it.

There are various substitutions you can make to the recipe so it depends on what you already have and what you want to end up with.
There are several of us that have done dual disc conversions and I think we've all done it differently for our own reasons.

My biggest reason is for the brakes but I also really like the handling on the fatbob. I don't really have anything right now besides my stock front end

As I understand it, a lot of the handling comes from the reduced rake.
That means you'll want the Fat Bob triple trees.
After that, you need to think about wheels. If you like the FB wheels (I don't) then you'll need the FB wheel(s), spacers, lowers, master cylinder, brake lines, caliper, rotor, hardware, fender, etc.
If you don't want the Fat Bob wheel, the Low Rider lowers can be substituted and then (I believe) any dual disc wide glide wheel can be fit.

There's also the V-Rod parts that can be used and many say are superior. I don't know much about that, tho. My understanding is the lowers and Brembo calipers bolt right up to any dual disc touring-style (wide) hub.
