I have a W-58 from a MA70R for sale. Roughly 200,000kms. Good condition although shifter is cut (quite short ). $450
Plus most conversion bits for same car. Master Cyl. Clutch Pedal, clutch line, hose bracket, hose, slave cylinder, flywheel and clutch (used but servicable). Basically everything except tail shaft. $250
Being an MA70, these parts are to suit a 7M-GE. You could run them on a 7M-GTE but Toyota used an R154 for this purpose.
