Old SJ Samurai or Vitara manual hubs for Jimny - which types are the best

I have a leak in my Jimny's vacuum system which operates its factory-installed vacuum hubs on the front wheels.
My battles with the issue are not going so well, so I am already considering to surrender and install manual freewheeling hubs.

I am aware that I can buy brand new manual locking hubs from JimnyBits store which are bolt-on compatible, but they are too expensive for my living standard. It is much cheaper to find old SJ 410 / 413 / Samurai or Vitara manual locking hubs on local junk yards, and install them.

I am aware that a spacer ring is needed in order to fit an old hub, and I am in a process of acquiring those.


Since there is a relatively wide choice of old hubs in local junk yards, my question is the following:

Which types or models of old Suzuki hubs would the be best (most durable and robust)? How can I identify those good ones?
I have been told that there are different models depending on construction materials of the hub casing, as well as of the hub locking switch and internal components.

Also, should I strictly go with manual locking hubs or can I use "automatic" locking hubs as I have seen on some Samurais and Vitaras?


One last question - will the screws of those old hubs be compatible with the Jimny, or perhaps I won't need them as I would use the screws supplied with the hub spacer rings?
