Its a pain, its do able, but a bit cramped. I did it the easy way and took the engine and gearbox out to change it.. lots of access then
it wasnt that bad when i did it, just get about 1 foot of extension bigs wth a socket on the end then attach it to a braker bar and your of to the races. Getting the lower nuts tricky but dooable, i think I had mine done in about 20 minutes , but my trans may have been out at the time, i cant remember.
