Need Suggestions for breaking loose Spring Plate Lock Nuts

I'm trying to adjust my ride height. One of the P O's had it all out of whack! The front was a breeze with the ol PB Blaster. The back is a different story. Anybody got suggestion on how to break loose the spring plate lock nuts? The torque setting for these nuts is around 175 ft.lbs!!
One other question, what kind of wrench is required to fit the eccentric bolt that adjust the height?
BTW it on a 1977 911S.

Thanks for any help!!

Break out the torches, Oxy/Acetylene is sure way to accomplish the bolt removal. Also, make sure they are workable before you go get an alignment. Good luck with it.

Automotion sells the tool for holding the large hex head on the back of the adjustment bolt. You must have this. It is a very thin wrench about 34mm. Heat the nuts to free them, you may need an extension on a 1/2" drive breaker bar.
