Do any of the kits allow using original lockout hubs for front disc brake conversion? Trying to keep the original look.

If you have original axles, with a tapped hole in the end, you can run the stock locking hubs with the bolts and washers included in this kit. Otherwise, the Wilwood kits re-use the stock drum hubs and spindles, so you could use the stock locking hubs with those as well.
