which bolts to undo?

^^Yes. My recollection is you have to reach up in with a box end and undo them a bit at a time. Not that difficult. You are going to want to allow for raising the engine a fair amount. That is if automatic, you might have linkage / kickdown problems might have to remove some of that. Drain and remove the radiator. They are no fun

Patience, and NO BEER lol
