I've converted one back to LHD, & have seen a few conversions (of varying quality
)
My CCW-353 had been fitted with a driving front axle & converted to RHD sometime in the 50's/60's. I took it back to LHD/6x4.
With a 6x6 it's a simple job to swap the steering arm from the LH side, with the upper cap from the RH side. That's the easiest part of the job!
The RH chassis rail was drilled to take the steering box, & the drag-link end cut, rotated 180 degrees & welded to suit the new position.
The steering box itself was removed, had the 4-bolt flange cut off, & a steel one brazed on at 90 degrees to the original, which allowed it to be flipped upside down & bolted to the RH chassis rail......takes a minute to visualize that, but it's right!
I remember space was short with it on the RH side.....I think the starter was the reason.
Master cylinder was swapped over & faced forward, with the pushrod set up to then operate directly from the front, instead of the original linkages working from the rear.
Most that I've seen just had the transfer case levers cut down to fit under your leg, but it's not very satisfactory - either for comfort or leverage when shifting.
Dash & glovebox interchange reasonably, transmission shifter offsets to the wrong side but is OK to use unaltered; & the handbrake is a bit more of a reach.
Cross-shafts have to be set up for the clutch & accelerator linkages, pedals etc.
There's a lot more detail I could recall if I thought about it, but that's the bones.
None of it's too difficult, just a lot of work.
I converted back for originality, & to gain a tighter turning circle - surprising power difference too
, not carting & spinning all the extra front-end gear.
