Both kits are fine.
However, OP needs to measure the piston diameters for both Front & Rear calipers and calculate the Pedal Ratio. From there, call Wilwood and buy a Master Cylinder that has the correct Bore and Stroke length for the entire setup.
No sense in dropping a bunch of money on new brakes if the MC doesn't provide the volume and/or pressure you need to squeeze them correctly.
None of this "15/16ths" or "7/8ths" guesswork BS. Do the math. Call Wilwood. Be happy.
