Just for the record, the default patter from any RAVE manual is to always replace the patchlock bolts
In 99% of cases its totally uneccessary.
I managed a socket on those front arm bush bolts. There is a specific angle under the car. I think I had my feet facing towards the front, and was lying right under the bush, with a torque wrench facing to the rear. My memory is so poor though, it could have been a little different.
Last time I did the bushes I think I disconnected from the hub, much easier as you can flap the lower arm up and down to align the bush with the subframe, and the bolts turn in by hand...
