as said it can be a pain in the arse

there is i rubber bung at the back of the sill , behind that is end of the torsion bar , you need a ford tool that screws into the end of the torsion bar and then bash it out with a slide hammer

most of the time the threads will have rusted away to nothing

the bushes are something like £20 each at a motor factors and i have a pair if you fancy giving it a go , was going to do them on a courier i had but as it was rotten i scrapped it
