Yeah they were actually working before believe it or not. I like the factory “4x4” center caps etcIdk why it says conversion but that's the same as what you have now.
You sure you want to keep those auto locking hubs. They aren't the most dependable. Course maybe after fresh cleaning and good grease will work better
80's auto locking hubs have nothing to do with vacuum (thank goodness). The best thing to do is sell them while they work and before you get noisy stuck hubs. It's really not much work to turn the dials and with a good front driveshaft you can shift the T-case in and out at will for mixed surfaces (keeping hubs locked).Thanks!!! I want to stick to the factory vacuum lockers
