one nut left on brake booster...help!!

[SDZR-1]

I have one nut left to remove to replace my brake booster...the top left ("left" as if you were sitting in the drivers seat). I can get my ratchet and socket in there and on the nut...but there just isnt enough room to move the ratchet back and forth. Can anyone give me some insight on which tools to use or a certain method that works for you. Thanks in advance.

Extensions and a swivel.

I remove the driver seat and put the steering wheel all the way up, and then crawl underneath with a socket, swivel, and then 2 long extensions. I put the socket & swivel & 1 extension on the head, then crawl back a little and attach the 2nd extension with the ratchet. For those of us with large hands & clostrophobia it can be trying.

well...i got it out after lots of frustration and back pain. The new one is in and I have the two outer nuts left to install, so decided to take a break. I didnt end up taking the seat out, but can see how nice it would have been. I just figured since I'm not a very big guy, I could wiggle my way in there. Anyway, I found a couple of swivels 1/4 and 3/8...and found the 3/8 easier to work with since it provided the extra leverage required to turn the nuts off. Thanks again guys for the pointers.
