OK, so since the diff head was still together I got a couple of old tapered end axles with threads/nuts on the ends & tried torquing one end while I had a really long spanner & my good lady on the other end. My torque wrench only goes up to 150 ftlbs & the sure grip didn't slip at that so do I just put it back in the car & go racing or pull it down & replace the clutches etc?
