Took out the rear shocks and leaf springs. Someone in the past did a rather shitty repair for one of the rear shocks where it had rotted and fallen through the trunk pan mounts, they made a bodge plate and bolted it to the rear frame. To get the leaf springs out was a little tricky; a couple of the front bracket mount bolts just turned as they had separated from a retaining clip, one of the bolts through the shackle at the back was rounded and both were rusted inside the spring. To overcome these problems I decided to go through the floor and trunk pans as this was quickest, easiest and are to be replaced anyway.
Troublesome bolt under floor pans holding the leaf spring mount bracket:
Cut the hole in the floorpan. Can now hold still the nut on this side of the bolt and loosen from the other.
Troublesome shackle mounting bolt for rear of leaf spring under trunk pan:
Cut the hole in the trunk pan. Now have room to fit a socket to make unbolting easier and be able to use a drift pin (another bolt) and a hammer to knock the bolt out of the bushing.
Shocks and assorted other bits taken off:
