66 Valiant, I want to put in front disk brakes, where do I start and a source for parts

I want to put disk brakes on my 66 Valiant. can i keep the small bolt pattern, can i use the spindles I have now? do I have to go power brakes? Where would I buy the parts from?

Yes you can keep SBP but that limits options

Some kits come with spindles but if you want to stay with the ones you have then that focuses your search

No you don't need to go power

There's a few threads in here on sourcing depending on your options and price point.

It's mostly personal preference and experience level on what works for you.

Good luck
