Tracks on Daihatsu Deck Van

Has anybody put tracks on a Daihatsu Deck Van 4x4 manual?

Is 4 Low an option on these?

Is Diff lock an option on these?

Looks like the front track install would be similar to the Suzuki Carry. How about the rear track, would it get in the way of the door or tailgate with a 2 or 3" lift?

Any info greatly appreciated.
