Default Front end/ brake install questions.



Hello! Friends bike, he wants to install dual disc. I'm not 100% sure what will work here.
Sliders have been shaved so buying new ones. It has 39mm forks. So what year slider/ caliper/ rotor setup should I be looking at? Will I be able to use these 11.8" take off rotors from a 2009 sg?
21" front wheel, 3/4" axle. 1/2" spacer on left side of wheel.
Guessing it is a late 90's early 2000's sportster or wide glide front end?? (originally a 1966 FLH)
Any help GREATLY appreciated. Thanks.

How you doing ... still need info?

What's the measurement between the Two Rotor Mtg Surfaces on that wheel? Also what's the size is that tire (besides being a 21")?


Btw, you can still get the 2000-later 3/4" axle 39mm Dual Disc Sliders NEW from HD

I think I have it figured out. Decided to go single disc, ordered some 39mm fork lowers (powder coated black) off of ebay. Still waiting on them.
Thanks for the reply.
