Too much work..
To get it started, put 2 bars or bolts in rear motor mounts, now between them, use a 2x4 and a wedge, or a pce of reddi-rod, with a nut on either end, then turn the nuts to spead ot (ie, jack it gently apart. Try clutch side, the long mount on chain side, could break with too much force..
When one end goes, the rest is easier..
