Upper Control Arms in Disc Conversion
When I did the conversion on my '69 Barracuda I used 73-76 A body disc brake UCAs. As far as I know they are the only UCAs you can use. They have to be off a disc brake A body 73-76!! I also used 73 and up B body spindles because they are more abundant and fairy cheap. You also need 73 and up B body LBJ. If I remember correctly I also used 73/74 Charger rotors and calipers (pretty sure).
