chuck some ropes under the motor then stand in the bay one person on either side lifting the ropes then gently rest it on radiator support and climb out then put on ground or in wheel barrow if you plan to move it around (skateboard also handy to wheel around on) motors not that heavy at all for 2 people

i think its 6 bolts for the box, you should be able to wriggle (violently) the box off the motor if all the bolts are undone and crossmember off, just dont drop it on youself when the thing comes out, stuff using the jack it will just get in the way and you will need to pull the box off the back of the motor before you pull the motor out if you intend to pull it out without gearbox

when you go to lift it make sure you have a pair of wire cutters handy, cause no matter how hard you check there always seems to be one wire you forgot to undo.

there is one other way to get motor out if your still not convinced, tryed it once worked a treat, undo all the crossmember and stuff letting the motor fall to the ground then roll the shell off the motor, just thinking this probabl wouldnt work for a 1200 though cause the motor wouldnt fit between swaybar and steering so youd have to undo those too, steering is a pig to undo!!!
