You need the rear uprights, half shafts and brakes with hand brake cables (DO NOT CUT THESE !!!) If like most you can't get the outer lower wishbone bolt to move let alone out cut through it with a cutting disk, you can always drill the rest of the bolt out later. If the top mount of the upright is completely shot replace with a 90A shore polyurethane replacement with a stainless crush tube with a 12mm through hole (these will be in my online shop soon).
This is what the TMXR wishbones look like when assembled with the upright in place, the gap will take a standard 34mm coilover.
