6x139.7 4Runner/Tacoma Swaps

[hino]

Hi team
Thanks for the add - been messing around with RHDs for years and ended up with a new (to me) 1987 4x4 5spd Cargo recently
Quickly noticing 5x139.7 is basically being removed from the planet
Brakes, wheels, diffs, etc - all becoming rare unobtainium

Has anyone swapped a 4x4 van with 6x139.7 parts?
Basically the rear axle and spindles from a 4runner/tacoma

Biggest hang up is the front 4x4 - most likely the Van control arms aren't compatible with 6x139.7 and nothing will bolt up

Curious what others have thought around this impending doom

There are bits and pieces of swap info adding 4Runner parts to Van, but I'd like to do away with all the discontinued parts, weird wheels and etc in one go

Thanks again!

4runner/truck rear axles are wider by a few inches necessitating customization to fit as well as wheels needing a front wheel drive offset again requiring custom wheels which is why there is virtually no aftermarket wheels and really never has been. The front may be adaptable to the 4runner/truck wheel hubs. I have done some research on this for a full float rear conversion like what is available from Front Range Off-road for the truck/4runner so I can add locking hubs to the rear and flat tow my van behind an RV and found bearing id's to be the same with the outer bearing calling for the same part # but have never checked spindle length/inner outer bearing separation distance to confirm. Even then you would have to look at brake disc offset and compatability with caliper mounting on the van spindles. All things pointed to a lot of custom work and I haven't pursued it further.

Interesting stuff - hard to find specs on these. Lots of 4runner/tacoma info around
Perhaps really you would need to go to RAV4 parts and 5x114.3 to stay Toyota, albeit that is all lighter-duty...really are unique vans

From what I can see even a Rav4 is too wide - also an AWD platform so no manual hubs...bolt pattern is too small anyways
Just comparing track widths
57.9 in for 1999 - https://www.cars.com/research/toyota-rav4-1999/specs/
59.1 in for 2005 - https://www.cars.com/research/toyota-rav4-2005/specs/

vs the 54.5 inch Vanwagon -

Seemingly not much around that fit's the bill at all
Only early 4runner/pickups have similar axle widths, but parts are scarce there too

From what I can see the Toyota Van is a JDM MasterAce
In the Toyota family, the bolt pattern originates with the Daihatsu Rugger, also badged as the Toyota Blizzard which was a direct competitor to the Suzuki Jimny/Samurai
The MasterAce/Townace truck is the result of combining the Rugger platform with the LiteAce platform
Rugger/Blizzard and Townace production stopped 1999, marking Toyotas end of using 5x139.7

Makes sense that here in North America, the Suzuki and Vanwagons match bolt pattern, but for reasons we wouldn't know


cheers
