Disc brake upgrade

I did the swap on my '70 duster a few years ago went with Wilwood some of the "best" money I ever spent no need to change the upper control arms like other kits,everything bolted right on you can retain your 4-bolt pattern or upgrade to 4 1/2 if you want the rotors/hubs are drilled for both bolt patterns and I still have manual brakes noticed a HUGH difference over the stock drum brakes..:thumbsup::thumbsup:
