The best way is that u have the correct tools to do the job , use an 30" extention 3/8 for the bolts that face into the engine bay , i used the gear wrench for the bottom ones the gearwrench had a piviot on the ring end .
Had driven the car then jacked it up to get it nice and warm and they fell off no problems .
Its a pitty that ur not in So Cal would help u out .
If u need help u can call me just pm ur number and would call u .
Also when it came to the O2 sensors be very very gentle , i stripped the threads on the sensor and had to buy a die to cut the threads .
