the 120k on my car in the Hobby Port at the local AFB (my gf's dad is active duty, he was helping by reading the directions as me and my gf's grandfather did the wrenching). We decided not to because I wanted to tackle it on a Saturday when I had to leave to go back home on Sunday. I was able to do the 120K in 8 hours @ home, never doing it before. The hardest part is going to be dropping the tranny and getting the stubborn bolts up top. Make sure you have several various sized extentions and swivel connections.
