if it's a 63a box,just get the front yoke from a stanza & put it onto the tailshaft.if you're moving the engine & gearbox back 2 inches,you'll have to shorten the tailshaft by that amount.the answer to hydraulic or cable clutch is with the 56 & 60 gearboxes,if right hand drive it's cable,if left hand drive it's hydraulic.with the 63a's it's all hydraulic.so where the gearbox came from defines how the clutch is operated.
