Brakes are same-same. Diff is different depending n whether the 7m-ge was manual or auto. Wheels are different. Dash is different. Depending on year tailights and grill are different.
Brakes work great with the right pads. Are single piston but BIG single piston with 300mm ventilated rotors at front.
Converted car is good option - if 7m-ge was aussie delivered the insurance can work out cheaper than an import!
Old converted car may have fuxored shocks/bushes/interior though.
