Velocity is right....!
Drop the beam, it is so much easier, the only ones that are a pig are the front beam mounts on the rear, i had to us plenty of soapy water and a hoooge vice to squeeze them in and again they look like you will never get the bolts in, however after a lot of swearing, scraped knuckles and thoughts of will it be worth it, they do go in!!!!!!!
I did mine on axle stands on the drive......and you will be suprised how quick you can drop the whole rear end!!!!
