Where did you get your front disc conversion?

I didn't have to change out my spindles or reuse the drum brake hubs. In my case using the drum brake hubs was not a good idea. The PO drilled out the drums for LBP and then WELDED the studs on back inside the drums. So if I had one stud go bad I would have a lot of work on my hands changing it out so I decided to do away with the problem altogether.
