Length is easy to solve

Arms and c hubs , knuckles etc from a Fujin 4WD MIni. Arms need to be drilled for attaching rocker link as it needs to be more vertical because of the short arms. The arms from the Fujin are not as wide on the inner hinge pin so spacers can be used to make the car LWB. Have not tried to set up for MWB. Not sure if I can get it that short easily. Drivesahfts are 30mm

Arm mounting blocks at this stage are 1C for the front and 1XA front rear and 1C for rear rear. It will only fit the Alfa Mito LWB body as it has a longer front overhang. THe LWB Mini Cooper body is too short in the nose

I thought of this idea but obviously others have already worked it out as well.
