When I was looking for pedals for my '73 I was warned that there were four different pedals used on Pinto's/Bobcat's.
1. 71-73 was one type.
2. 74 to ?? manual brake was another
3. 74 to ?? power brake was another
4. Don't know.
Also, just a guess but Mustang II pedals might work. For me the bad news was I bought 79-80 Pedals for my 73. The good news was Fred Morgan needed them and swapped me for a 71-73 set.
