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:
I did exactly the same thing. Also upgraded to the Wilwood master cylinder. I had the original Kelsey Hayes disk brakes but these stop WAY better than the Kelsey Hayes ever did. Just a note if anyone has to upgrade from the Kelsey Hayes to Wilwoods, you will have to downgrade your spindles and lower ball joint to drums.
