I believe you are correct, Skidoo... i think this can of worms may be more like pandora's box.
Just out of curiosity... you mention "earlier models w/o ECU/ABS" - Do you happen to know of any Toyota electric MC's w/o ABS? That could solve my challenge, if it exists!
that won't work. I physically cannot install the unit w/ the ABS control module attached. So i need to find a way to convert the MC to non-ABS. But looking at the hydraulic diagrams, I'm not sure it can be done??
Sorry for taking this thread in perhaps an odd direction, but I've been working on adapting this MC/Booster to a Tacoma. Does anyone know if it's possible to completely eliminate the ABS control module? My application doesn't require ABS... and frankly, I need the room (i.e. the control model...

Stop overthinking... let's do some math...
Narrow axles are 55"
IFS Axles are 58"
most aftermarket wheels are 3.5" backspacing
So if we do some math, running a 2" backspaced wheel on a narrow axle is effectively the same as running a 3.5" backspaced wheel on an IFS axle...
