I got all the nuts off in about an hour. Some you can get from the top and others from underneath. Apart from standard sockets and wrenches I used a ratcheting 5/8 and 3/4 wrench because they are good when you have limited room to swing it. I used a stubby 3/4 for the isolator nuts.
I also found some old Schumacher engine mount shims leftover from another project 15 years ago!
