dropping the fuel tank to get at rear control arm bolts

I noticed the bushings on my rear CA's were in horrible shape on the drivers side so I ordered up a set to replace all 4 on both sides.



Has anyone done this on their own?



I know the tank needs to be dropped to gain access to the bolts on the driver side, but does it need to be disconnected and removed all the way or can I leave everything intact and just drop it a few inches?
