96 Audi A6 {base} - Replacing Front Sway bar/anti-roll bar bushings
 

I have 96 A6 base edition and I am trying to replace the front sway bar bushings, as they are deteriorated. The problem I am having is getting the second nut off, it just keep spinning(I had to place another 3/4 socket thru a hole on top of the subframe) while using another socket to remove the nut. However with the second one, there isn't enough clearance to get socket in the hole let alone the ratchet. I was thinking maybe an offset box set wrench might fit and hold the second bolt(but it might not be deep enough) without lifting the engine to remove the subframe to get to that second hole. So... The question is - Any Ideas on how I can accomplish this without having to lift the engine?

If I can get the second nut off the mount bracket would I be able to get it back on after replacing the bushing without having to move the engine to lower the sub-frame... please help I don't wanna take it off and not be able to get back on!!!
