I am going to be switching from drums to disc brakes over the winter for my '69 Nova. I was just wondering, who has the best prices for a 4 wheel disc brake conversion? I don't need the absolute best out there, but something that will perform much better than my drum brakes now. I have seen kits on eBay for around $800 for 4-wheel conversions. Is there anything cheaper? Also, I have heard that putting on disc brakes makes the tires come out a couple more inches than they would with drums. Is this true?
