i did my LC on ramps, took about 15 mins, my bro in law did my LCR on stands whilst changing my oil (he had nothing to do so i got his hands dirty lol) and he did the mount at the same time, it was only when he passed me a mashed black bush that i relised he had done it lol
 
My mate did mine on ramps in his garage. Took about 20 mins I think. The bush has to be torqued on to the correct settings otherwise you get insane cabin vibration..

Any vibration I had soon disappeared, but at the end of it I've got almost no wheel-hop now :)
