That's great to know, thanks. My next question is the rear spring / diff assembly swap over. The car is only 8000 miles "old" since it was apparently fully professionally restored at great cost in 2015 for the PO and the mechanical bits, as far as I can see, look great. So for the entire rear end swap, springs, diff etc etc, is it practical simply to jack up the car, wheels off, disconnect brake cables, prop shaft etc, support the weight, undo the few bolts between the chassis and the spring / diff etc and carry it over to the other chassis, simply bolting it back in place there?
