Information on Wilwood Disc Kit

Has anyone gone to the disc kit by Wilwood (140-15468-DR) And have any opinion.
Wilwood Disc Brakes - Front Brake Kit Part No: 140-15468-DR

My Scamp has the 'factory' disc's from a '73.
I have ordered the Wilwood 'Big Brake Kit Forged Dynalite' for the front, with the SS Braided 18" Lines.

I was curious if anyone else has gone this way? They are suppose to go directly on the 'stock' spindles, do they? any opinions?
