Last time I tried I found it to be a bitch to get to the nuts to unscrew them.
Any advice/tip besides just “giving 'er” :rolleyes:
Torch/
hammer. combination of torch hammer and wrench, and little bit of jus’ give 'er 
ive had my backs off before
spak them the night before, use lots of lube
and then get vice grips and lock them on TIGHT and then spray on more lube
wiggle them back and fworth hard so it starts to crack the shit thats around them and break them free
keep spraying lube and eventually you feel it start to give and then carefully turn them , unlock vice grips
lock them and turn again
then use a 10 mm very carefully to turn it the rest of the way off
