I've probably changed engine trans combo's a hundred times in my life. Up until I was in my 50's I always used a set of tri-pods with a block and tackle my Pap and uncles used for semi work. A screw driver in the right chain link was all I ever needed to set the angle , get it wrong? move it to another link. This isn't rocket science it's a pretty easy procedure ESPECIALLY when you take advice from someone with more experience trying to help you .TRUST ME (and others) bolting everything together out on the ground and then installing as an assembly is the way to go.
