Steering Conversion Kits - which one?

[Old Timer]

Have a: 1966, 170 v6, 3 on tree and looking to move from manual to power steering (mainly in town driving). What are the major differences in the below kits? Leaning toward James Duff based on price. Thanks for the help!!

Are those kits for a 6 cylinder? Last I knew of it bc broncos was the only one with the ps bracket for the 6 cyl. The other kits are for small block v-8s
